Legacy Audis of 1987-2000 Are Protected by the K&N 33-2029 Engine Air Filter

K&N 33-2029 replacement washable air fitler for Audi

The K&N 33-2029 engine air filter will replace the stock air filter and is constructed of a special cotton gauze that presents a greater surface area to trap more dirt and other particles.

Audi owners are part of a storied automotive design and engineering fraternity, and if you own a 20th century example built between 1987 and 2000, you appreciate it as a legacy car, a vehicle at the top of the sporty, sophisticated driving scene of its time. A number of models from that 13-year period have been voted "best of all time" by web entities such as Ranker and Complex.com, which use input from fans and experts, requiring voters to have the car's practicality, reliability, and performance in mind, and their community-based survey results seem quite relatable. Especially appreciated are the A6, the 1989, 1990 and 1991 Audi 80s, the 1986, 1989 and 1990 Audi 100 Sedans, the 1991 Audi 90, and 1996-98 Cabriolets.

Of note are Audi's innovations from that time, such as aerodynamic flush windows in the C3 100 of 1991, and a fully zinc-dipped, galvanized body for the new type 89 in 1987 (also called the 80 and 90, in North America), which are design and manufacturing practices still in use today.

Development of both lightweight, high-performance diesel- and gasoline-powered engines at this time revolved around Audi's in-line four- and five-cylinder motors from 1.9 to 2.3 liters in size, plus new 2.6- and 2.8-liter V6s and a new 1.9-liter TDI (turbocharged direct injection) diesel. It was quite a range that was mostly available only in Europe, but North America did get the V6 and TDI.

The Coupe and Cabriolet came along in 1988, based on the Audi 80 platform, and the 1990 Coupe made it to North America as a Quattro GT car with the 20-valve, 1.3-liter 5-cylinder engine. The Cabriolet, based on the Coupe, and Audi's first convertible since 1959, was powered by the 2.8- and 2.6-liter V6s.

Although emissions and old-car regulations keep many vehicles over a certain age off the roads in Europe and the UK, yours is a survivor, and that is because you've maintained it well and driven it carefully. Among those maintenance details is the engine air filter service which has been made simpler and easier for some time by utilizing the K&N 33-2029 washable, reusable engine air filter.

Box for K&N 33-2029 replacement air filter

An engine air filter service is something you can easily do yourself, or you can order up the K&N 33-2029 filter and 99-5000 cleaning kit for your mechanic, and be assured you are giving your early-generation car the best protection on the planet.

The range of engines for the specific 1987-2000 Audis listed below is varied, but those included all share the same basic air box shape and dimensions that can hold the same open-top, rectangular air filter that can be replaced by the K&N 33-2029. Why keep buying disposable air filters when you're in preservation mode with your elder Audi?

K&N engine air filters are designed and engineered to replace the stock air filter and are constructed of an oiled, cotton gauze filter medium that presents a greater filter surface area to trap particles and bring more air to the engine. The filters are designed to provide more horsepower and torque for crisper throttle response, a plus for any iteration of your favorite marque.

The 33-2029 is recommended to be cleaned at 50,000 mile intervals, depending on driving conditions. It also can be cleaned more often if you wish. The process is very easy and requires only simple hand tools. A set of printed instructions accompany each K&N filter, and depending on your model, there are also videos available online to walk you through the procedure.

The best way to clean this filter is with the K&N 99-5000 filter care service kit. Spray the filter with Power Kleen spray, rinse in clear running water, let it thoroughly air dry, then re-oil it with a few sprays of the air cleaner oil before refitting. Or you can simply specify the K&N 33-2029 filter and 99-5000 cleaning kit to your mechanic for the next scheduled service.

You appreciate what your vintage Audi can do for you daily and what it has done throughout the decades on road and track. The engineering successes and innovations built into your passenger car makes it a superior road-going vehicle that you can love forever. To ensure that your Audi stays reliable, invest in the K&N 33-2029 engine air filter, which is backed by K&N's 10-year, Million Mile warranty.

When you're ready to buy a K&N replacement air filter, first use K&N's online search by vehicle tool, then visit an authorized K&N dealer, who can be found worldwide using the K&N dealer search.

K&N's RK-3932XB Air Intake System Adds Horsepower and Torque to Your Harley-Davidson®

K&N RK-3932XB installed on 2016 Harley-Davidson Switchback

The RK-3932XB intake on a Harley-Davidson

Harley-Davidson motorcycles often respond more profoundly to simple performance modifications than motorcycles with other engine configurations. In stock form, Harley-Davidson engines are “under stressed.” What that means is that the engines are designed for a rather conservative balance between reliability and pure performance.

That’s where K&N’s RK-3932XB comes in. The product is one of K&N’s Street Metal series high-flow air intake systems. In short, the system helps your Harley® breathe freely resulting in a potentially substantial power advantage. The RK-3932XB is a complete intake system that replaces the restrictive stock unit. The air filter in the system is extra tall, which markedly increases airflow. The oiled cotton gauze filter media not only increases flow, but it also extends service intervals. You know you’d rather be riding your Harley than servicing it.

Installation of the RK-3932XB could not be more straightforward. The custom aluminum backing plate and vibration absorbing gasket fit securely to the throttle body and feature an internal-run breather system. Once installed, you can realize an estimated 7 horsepower gain at 4662 RPM (as dyno tested on a stock 2016 Harley-Davidson Dyna Switchback 103 ci). That performance boost is the kind you’ll feel instantly. Interestingly, that horsepower gain is more than the first Harley-Davidsons produced in total! The intake unit is especially well suited for custom or large engine builds that truly need that extra airflow.

The clean lines of the RK-3932XB intake system

The air filter unit on a Harley is a centerpiece of the engine design so it has to be good looking. The RK-3932XB has a subtle, clean appearance. The iconic K&N red-oiled filter media is visible behind the understated black intake cover. The overall aesthetics of the intake speak to its “all business” design and performance.

It should be noted that over the life of the motorcycle, a K&N washable filter is a cost effective alternative to restrictive, disposable filters. Moreover, in a time when our landfills are being loaded with throw-away maintenance items, a reusable K&N filter such as the E-3986, which is the part number for the filter, is an environmentally responsible choice.

The RK-3932XB is made in the USA and is covered by K&N’s exclusive Million Mile Limited Warranty. With easy installation, proven power gains, extended service intervals, good looks, and legendary K&N quality, the RK-3932XB is a great option for Harley-Davidson owners who want more out of their V-twin.

Milton Peters' Custom Chopper is a Celebration of Beauty, Speed, and Power

Custom chopper with 127ci motor and K&N filter

Milton Peters’ stunning Green Monster is protected by legendary K&N filtration

Milton Peters’ stunning chopper is named after the iconic left field wall in Fenway Park. The bike’s designer and builder says he has always been a “huge Boston Red Sox fan.” In reality, Peters’ “Green Monster” shares very little in common with its namesake other than color. Fenway’s version is tall, stationary, and silent. Peters’ version is low, fast, and anything but quiet.

Leaving well enough alone is not in Peters’ DNA. “I started building, modifying and ‘chopping’ anything with wheels as a kid and then into my teenage years,” he reflects. Even with the success of his Green Monster, Peters is quick to deflect the label bike builder. “I was never a bike ‘builder’ until this project. There are plenty of custom parts on the bike, but I am still more of a novice assembler and far from the talents of many amazing builders. The amount of respect I have for any builder / assembler or even the everyday repair gurus is very high.” While Peters’ humility is refreshing, the quality of the build and the incredible visual unity of the chopper speak to a deep-rooted talent.

Custom one off exhaust on chopper

Serious work went into these exhaust bends, and it was worth it

In reality, the lion’s share of Peters’ customization experience has come on four-wheeled vehicles. “I have built and customized import cars that were featured in international magazines and even built an Isuzu Pup mini truck and fabricated my own body drop and installed my own hydraulics despite never have used a torch or welder before, and created a full custom stereo. I have been more heavily involved in the aftermarket automotive, recreational vehicle, and electronics scene for about 20 years now.”

According to Peters, the Green Monster is a product of about 15 years of thought, planning, and mental incubation. All of that rumination is evident in the overall aesthetic unity of the creation. Let’s start with the paint. As for all those green bits on the chopper, Peters says, “I wanted the paint to be candy for sure. I wanted the paint to scream ‘extreme’ yet not be too busy.” The color is not the end of the visual feast as Peters thinks his paint details make the difference. “I feel that this custom candy green paint, the skull on the tank, the flames and then all of the small elements that match throughout the entire bike, are what makes this bike different.”

K&N filter inside S&S intake housing

The K&N filter inside that intake helps those big jugs pump out serious horsepower

Peters knows that a great chopper is not just about paint, despite the societal influence of what he calls “the commercialized chopper scene.” While that fad has faded, Peters is quick to point out that chopper building is alive and well. He says, “There are still plenty of shops, plenty of garage projects, or even people like myself who just finally said, ‘I am going to do this and I am doing it because I want to.’” The details of the Green Monster go much deeper than that paint.

The bike’s exhaust is a primary styling, performance, and auditory element. Getting the pipes just as Peters wanted them took some work. “I wanted the old school, heat wrapped look while having a slight ‘up sweep’ to it and of course an aggressive idle and rumble. I took a new exhaust and heated the bends. First, I had to get the exhaust past the housing, and I also wanted to sweep it up and out more. Next, I heated both pipe ends and brought them together slowly. I made a new bracket to mount them together and it works out visually and sounds exactly how I want it to.”

Custom open primary with 3.5-inch belt

Attention to detail is everywhere on the Green Monster

Peters wanted other design details to “match and be stand out items, but be subtle.” Many of those details are machined to match the chopper’s distinctive rims. The brake rotors and drive pulley are cut to match the wheels. Proving no detail is too small, even the valve stems are machined to match. “The bike features a black frame with a good combination of chrome, black and aluminum throughout.” Peters continues, “The S&S intake with the K&N filter even has a chrome housing and I added in the black accent cover to the face of that. It is pretty clear that I wanted the bike to flow nicely. I feel the bike has a great balance of the three metals - chrome, black, and aluminum.”

So what about the engine in the beast? Well it’s impressive. The big twin pushes a displacement of 127 cubic inches. It has forged pistons and roller rockers. The power-plant produces approximately 160 horsepower and more than 150 foot-pounds of torque. It delivers that power to the road through a 6-speed, right-side drive and an open primary with a 3.5 inch belt drive.

Custom chopper with pearl green paint

The sexy lines of Milton Peters’ creation are the result of years of visualization

Peters trusts K&N to protect his fire-breathing labor of love. “I truly have used K&N for many years. My first oil filter and air intake were K&N back in 1997. I have trusted them ever since. The washable and re-usable part is nice but to me the performance and instant throttle response I feel from the K&N air filters and intake systems is worth it all. In my daily drivers and in my motorcycle, I know I can trust the all of the K&N filters to perform.” Of course, K&N has a full range of filters and intakes for your particular project. Use the online application tool to get what you need.

With the Green Monster complete, what’s next for Peters? “I have contemplated selling this chopper and building another; maybe a bagger. But then literally every time I look in my garage I smile. So I am often torn. That being said, I also think I may build something again with 4 wheels, maybe a hot rod, muscle car, or extreme 4X4. The jury is still out.” Whatever Peters decides to tackle next, rest assured that it will be unique, it will be fast, and it will be fitted with K&N products.

Noah Gragson in the No. 7 car leads the field in the NASCAR K&N Pro Series West race at the Utah Motorsports Campus

Noah Gragson swept the K&N Pro Series West doubleheader at the Utah Motorsports Campus and returned to victory circle for the first time since June.

“It feels good to sweep the weekend,” Gragson said. “This is what we needed. Heading off to the next race, we got a road course in the East Series. I’m just really pumped up right now.”

Gragson, one of the NASCAR Next drivers, won the first race after leading the last 10 laps of the Utah 110 presented by Ken Garff Volvo. He won the second race taking the lead on the last lap of the race.

“This is pure, never give up attitude,” Gragson said. “We really need this as a team. I am just so pumped up for all my guys, they worked real hard for this.”

Noah Gragson, Todd Gilliland, and Ryan Partridge on the podium

Noah Gragson, center, won the second of two NASCAR K&N Pro Series West races at the Utah Motorsports Campus. Todd Gilliland, left, was second, and Ryan Partridge was third

In the first race, Ryan Partridge won the pole and led the first 22 laps of the K&N Pro Series West race. Rookie Todd Gilliland, the leader in the K&N Pro Series West standings, passed Partridge on lap 23 and was out front for three laps.

Gracin Raz was third, followed by Julia Landauer in fourth and Riley Herbst in fifth.

Gragson took the lead from Gilliland on lap 27 and won the race by 1.086 seconds. It was Gragson’s fourth win of his K&N Pro Series career. He won the K&N Pro Series East race at Stafford Motor Speedway in Connecticut in June.

“Made my way into second chasing the 16 car (Gilliland),” Gragson said. “He made a mistake down in turn 1 with probably 11 or 10 to go. I took away the lead and I think that was the game-changer in the race. That’s what changed everything. Got some momentum on our side just being the leader. He really burned his stuff up there trying to run me down. He’d get close and then blow the corner, get close again and blow the corner.”

Gilliland said his inexperience on road courses mixed with his aggressive strategy to catch Gragson cost him in the race.

“It’s my first road course. It’s no excuse,” Gilliland said. “I kind of overdrove it, kind of got off track. I let the 7 (Gragson) pass me. I got back to him and I overdrove it again and let him get away.”

Noah Gragson won the NASCAR K&N Pro Series West at the Utah Motorsports Campus. It was the fifth K&N Pro Series win of his career. He won the K&N Pro Series East race at Stafford Motor Speedway in Connecticut in June

In the second race in Utah, Partridge won the pole again, his fourth of the season. This time he was out front for five laps before Gilliland, who started on the front row, passed him. Gilliland and Herbst battled for the lead over the next 30 laps before Gragson passed both of them on the final lap.

“I just ran my race. Stayed focused, stayed positive,” Gragson said. “That’s really all I could do. Had a really good car, just one race on those tires. I’m really pumped up for my team, two in a row this weekend.”

Gragson won the second race with a 3.809-second margin of victory over Gilliland. Partridge was third, followed by Herbst in fourth and Todd Souza in fifth.

Ryan Partridge won the pole at Utah Motorsports Campus

Ryan Partridge won the pole for both NASCAR K&N Pro Series West races at the Utah Motorsports Campus

“I thought I put my team back in a hole, messed up on a restart about halfway through running fifth,” Gragson said. “I was feeling down, but my crew chief told me that we were still in this thing, just really happy for these guys. Made my way back up and kept fighting till the end.”

Gilliland has a 13-point lead over Partridge in the K&N Pro Series West standings with two races to go. Gragson is 37 points behind Gilliland and in third place.

“It feels good,” Gragson said. “This is what we needed momentum wise. The guys worked really hard for it.”

The next K&N Pro Series West race is at Meridian Speedway in Idaho on Sept. 24.

K&N Driver's Mike Maier and Jake Rozelle Go Head-to-Head at Circuit of the Americas

Jake Rozelle and Mike Maier at Circuit of the Americas

K&N driver's Jake Rozelle with his 1969 Camaro and Mike Maier with his 1966 Mustang at famed venue Circuit of the Americas

Possibly the most fun we've had out on the track this season would be witnessing the friendly rivalry between the Optima Search for the Ultimate Street Car series GTV Class K&N sponsored drivers Mike Maier, in his 1966 Ford Mustang and Jake Rozelle, in his 1969 Chevrolet Camaro. What makes this so much fun is just how closely matched they are when it comes to talent and speed. And really, who doesn't like seeing a Ford and Chevy throw down?

Jake, a recent graduate from the University of California San Diego with a Bachelor's in Science and Engineering, is young, scrappy, and super talented behind the wheel of his 1969 Camaro built by JCG Restorations. As potentially the youngest competitor in the OSUSC series, there isn't much that can stop this talented K&N driver from grabbing a podium at an Optima Series event. Over the past few years we've watched Rozelle grow up before our very eyes. We've watched as he became a household name thanks to MAV TV and Optima Search for the Ultimate Street Car television series. He's beguiled us all with his charm and winning smile.

The Maier name has long been associated with motorsports. Collectively, the Maier family has more than 46 years in racing. Mike has enjoyed a longstanding relationship with K&N. Whether as a competitor in USAC as a K&N team driver in the Ford Focus Midget Series or being a brand ambassador in SCCA as a national champion with numerous trophies to show for it Mike is definitely a guy who can wheel a car. Talented and earnest, he's been racing most of his life. But he's not just a driver. Mike is a family man and business owner. For the past two years, he and wife, Brianne, have spent almost every waking hour building and growing their new business, Mike Maier, Inc. So when he's not racing on the weekends, you'll find him at the shop designing, engineering, and fabricating suspension and chassis parts for his customers. Maier's specialty? Track tested, Maier approved, Mustang Performance Parts. Certainly no surprise there.

Attention to detail and focus creates a great driver. Rozelle exhibits both

If you've been to an Optima track event or even a Goodguys show you've seen both of these fellas hanging it all out for the win. While Mike is a more seasoned racer with 20 plus years of racing experience, Jake comes to the track with an indescribable intensity that comes from youth. We've all been there. That sense of invincibility and the idea that we can conquer anything life throws our way. A certain confidence that far too many of us outgrow. But don't count maturity and wisdom out just yet. Mike brings his years of racing experience to the track that ultimately translates into him being a worthy opponent.

The seventh installment of qualifying events for Optima Search for the Ultimate Street Car challenge, presented by Advance Auto Parts, made its way to Austin, Texas, to the famed F1 venue, Circuit of the Americas. Jake was primed and ready to go. This year he is gunning for number one spot as points champion for this Optima series and has now attended four of the series qualifying events. In fact, he has earned a first place finish at his first three events. Having father Roy, along with JJ Furillo of Ultimate Performance trackside, has made this adventure better in all ways, from improved car performance to great fatherly advice and coaching, Jake has really shined throughout the season.

From chassis tuning to alignment adjustments, Maier would do anything he could to catch Rozelle in autocross

While this is only Mike's second Optima event this season, he has taken time to make major improvements and killer mods to Ole Blue that would ultimately benefit him at COTA. His latest suspension designs, along with widened stance, and fatter Falken tires, provided better grip on the track in the Texas heat. Maier went to Texas on a mission, to get the invite. The coveted invite to the Optima Series finale, OUSCI immediately following SEMA. The question on everyone's mind was could he do it?

Day 1 at COTA saw the largest field of drivers competing this season at any one event. The field would be split between the Detroit Speed & Engineering Autocross and Powerstop Brakes Speed Stop challenge. Jake and Mike started at autocross together. This allowed them the opportunity to keep tabs on each other's lap times, and made for some healthy competition. One pushing the other a little more, a little quicker. After the first few runs Mike felt a severe case of understeer in Ole Blue, so he and his team got to work tuning the chassis. However, tuning was cut short between runs by an odd brake pedal/master cylinder problem. Turned out that a problem with the balance bar and alignment caused one pushrod to bend, then during another run a second rod would bend. Fortunately, they got the issue fixed and before the session was over Mike would get his quickest lap time of 29.749. Jake, refusing to give any ground, would get his lap time down to 29.551 a crucial 2/10th's of a second faster, earning him a first place finish in the GTV Class at autocross, as they headed over to the Speed Stop Challenge.

Jake gave it everything he had in autocross and came in 1st in GTV Class with a lap time 2/10th's of a second ahead of Mike

At the Speed Stop challenge, these two racers threw down the gauntlet. Every run would see Mike and Jake swapping first and second position, back and forth. Jake was pushing his 1969 Camaro to the max with each run, but Mike had Ole Blue just where he needed her to be competitive. It was only a matter of time before the clock would run out and Maier would claim victory, by 2/100th's of a second! Talk about cutting it close!

The next component these gentlemen would compete in was the Lingenfelter Design & Engineering segment. Maier has struggled a bit in the past with his scores in D&E. Mike admittedly focuses on performance and function first over form. It appears though, the judges approved of his recent mods and upgrades to Ole Blue. Rozelle on the other hand has regularly been rewarded with high scores as his Camaro always seems to please the judges. As per usual, Jake received a high score of 96 points, in a tie for second place with Kevin Tully, who also received 96 points for his 1964 Plymouth Valiant. In an incredible three-way tie for third place, Mike Maier would receive 93 points in Design & Engineering for Ole Blue, alongside Craig Johnson with his 1963 Ford Falcon and Larry Woo in his 1968 Chevrolet Camaro. A definite first in the Optima series event.

Saturday's fun concluded with the Lucas Oil Road Rally. After a scorching triple digit day, with humidity off the charts, the drivers were treated to a rather simple rally consisting of just 1 checkpoint at Advance Auto Parts in Austin, and a mere 24 mile round trip adventure. We are happy to report that each of the drivers made it safely back to the track with smiles on their faces.

Day 2 at COTA meant it was time for the Falken Tire Hot Lap Challenge on the infamous F1 Road Course. Drivers were scurrying to make last minute adjustments to their cars and installing their transponders. Road course would literally consume the whole day and there was no sign of relief from the heat. It would be imperative for these drivers to not only pay attention to their cars response to the triple digit heat, but to pay attention to their body's response to the heat, as well.

First order of business was the driver's meeting with the typical pre-track talk, where to pass, flags and what they mean, use the whole track, big speeds and by all means don't crash and burn! We spoke to Jimi Day, USCA Race Director, and he shared that this Optima series event was the very first of its kind here at COTA. During the driver's meeting he would emphasize safety and encouraged the drivers to make note of this unforgettable experience, because it's not every day you get to race your street car on an F1 course!

Maier’s new, wider stance and lunch time spring and chassis adjustments brought the Speed Stop Challenge home for the win in GTV Class. Just 2/100th’s of a second faster than Rozelle

The drivers would be broken down into three groups: novice, intermediate and expert, with Jake and Mike being part of the expert run group. Each group would have four run sessions in which to lay down their fastest lap time of the day. They would take part in orientation laps to familiarize themselves with the road course, then the fun would begin! On Maier's first session out, about a half a lap in, Ole Blue lost a bolt out of the shift linkage leaving the car stuck in 4th gear. This left him three run sessions to work with in effort to catch Rozelle, who seemingly was problem free in his Camaro. Maier would start his second session at the back of the pack and have to work his way through traffic as a result of the first sessions mechanical issues.

We could see in the second expert run session, both of our K&N drivers were getting really comfortable with the track. In fact, for every improvement Mike made, Jake also improved, running smoother and faster with each lap. By the third run session the heat was beginning to take its toll on the other cars and drivers. We watched in horror as a late model Corvette caught fire in the paddock area. Fortunately, the hood was the only casualty. Before Maier headed out, he made a sway bar adjustment that proved to be the right move. He knew if he was going to beat Jake he would have to get after it. But Jake would not lay down and he made Mike work for every tenth of a second. In the final run session, Maier would make one last critical adjustment before heading out. And then it happened. He would drop another full second off his lap time, ending him at a lap time of 2.29.0 which was enough for him to leapfrog to first overall in GTV Class for the weekend.

Mike Maier driving on the hot lap challenge

Falken Tires Hot Lap Challenge saw some challenges throughout the day. But Mike Maier, brought ALL of his years track experience to the course and came out the victor in GTV Class, ultimately securing him the overall win by just one point

The question on everyone's mind, could Mike Maier take the overall win from Jake Rozelle? The answer? YES. Mike Maier, with all the challenges and mechanical issues he encountered, was able to come away the winner overall in the GTV Class securing him the invite to OUSCI. It didn't come easy though. Jake Rozelle is a force to be reckoned with and never backed down. Only one point separated first from second place in GTV Class and in the end these drivers put on one heck of a show.

Even with the incredible heat and humidity, plus the on-track and in-paddock mishaps that took place at COTA, all of the drivers said they'd come back to Austin, Texas, to once again run the Optima series at Circuit of the Americas. Each of them leaving with memories of a lifetime, regardless of where they finished. Congratulations to Mike Maier on his COTA win and to Jake Rozelle for his continued point lead in GTV Class. We'll see you two at NOLA for the 8th installment of the Optima series qualifying event and will be cheering you on.
