Boost The Efficiency of Your M50-Powered BMW with a K&N Air Filter

K&N Replacement Air Filter 33-2070

The K&N 33-3035 air filter will increase air flow by as much as 50%, and is designed to add power to your M50-powered BMW.

Some of the features that many car companies are touting on their current cars or have added them in recent years include lightweight grey iron cylinder block, aluminum cylinder head, four valves per cylinder, zero-clearance hydraulic lifters, hollow camshafts, coil-on-plug ignition system, dual spray pattern sequential fuel injection, and a composite intake manifold. All of the features listed were part of the BMW M50 in-line six-cylinder engine first introduced in 1990 (an amazing 26 years ago!).

Well-respected for its engineering, durability, high output, and smooth operation, the M50 has won Engine of the Year accolades in Europe, North America and Asia. And even though the horsepower of the M50 has always been high, it can be improved upon with a K&N replacement air filter 33-2070.

K&N Replacement Air Filter 33-2070

Besides basic hand tools, everything you need to install a K&N replacement air filter in your M50-powered BMW is right in the box.

In terms of specifics, the BMW M50 is an inline six cylinder engine that was produced from 1990-1996. It was first introduced in the E34 520i and 525i, replacing the M20 engine. It began to be phased out following the introduction of the M52 engine in 1994.

In September 1992, the M50 was upgraded to M50TU specifications (which stands for Technical Update), which added variable valve timing to the intake camshaft (called single VANOS by BMW). Applications include the 5-Series, 7-Series, M3, Z3, Z4 and others.

The K&N 33-2070 replacement air filter has been specifically developed to increase up to 50% more air flow, which is designed to add power to your M50-powered BMW. More air flow coming through the filter can result in improved response when you step on the throttle, and more torque throughout the operating range of the engine.

K&N air filters are assembled from multiple layers of a unique oiled cotton filter media, rather than the easily-clogged paper used in many original equipment and replacement filters. The oiled cotton construction not only allows for increased air flow but also provides excellent filtration properties to ensure your BMW’s long engine life.

The only maintenance required for a K&N replacement air filter is a service you can easily do yourself. At up to 50,000 miles of driving (depending on your driving conditions) use a 99-5000 K&N air filter cleaning kit to clean and re-oil your air filter, bringing it back to like-new condition and ready for another 50,000 miles of driving. Your one K&N air filter is designed to last for the lifetime of your vehicle, which K&N guarantees will perform for up to 10 years or 1,000,000 miles without requiring replacement. For full details visit the K&N Million Mile Limited Warranty.

You can order the filter simply using the part number 33-2070 as well as order the air filter cleaning kit 99-5000.

To find additional K&N upgrades for cars, trucks, scooters, motorcycles, motorhomes, or almost anything with an engine, use the K&N Search by Vehicle tool. Find an authorized K&N dealer nearby using the K&N Dealer Search.

Even High Revving Hondas Gain Efficiency with a K&N Air Filter

K&N Replacement Air Filter 33-2104

By increasing the flow of air, K&N replacement air filters are designed to give better throttle response and improved torque at all points of your Honda engine’s operating range.

This pair of Honda engines is reminiscent of the television infomercials where the announcers read “but wait, there’s more.” Both the Honda D and K engines had long service lives in a surprising variety of vehicles, with any number of versions to suit the applications. Clearly, not only were they well designed but ongoing R&D kept their performance at the level of newer engines. What’s surprising (or maybe not) is that all these applications utilize the same K&N replacement air filter 33-2104.

The Honda D series inline four cylinder engine was installed in a number of different of models, most commonly the Honda Civic, CRX, and the first-gen Acura Integra between 1984 and 2005. Engine displacement ranges between 1.2 and 1.7 liters. The D Series engine was constructed as either SOHC or DOHC, and was at times fitted with Honda’s VTEC variable valve timing system.

K&N Replacement Air Filter Box

Everything you need to install a K&N replacement air filter in your Honda is in the box.

The Honda K series engine is also an inline four cylinder engine introduced in 2001. The K series engines were equipped with dual overhead camshafts and utilized roller rockers to reduce friction. The engines use coil-on-plug ignition for each spark plug. This eliminates the need for a conventional distributor in favor of allowing the ECU to control ignition timing based on engine sensor inputs. Two versions of the Honda i-VTEC system have been used on the K series engine, one optimized for fuel economy, the other performance.

And once you’ve installed your K&N 33-2104 air filter you’ve eliminated the need to purchase and replace paper filters for the life of your Honda. The only maintenance needed is a service you can do yourself in just a short time. At up to 50,000 miles or 80,000 kilometers (depending on your driving conditions) clean and re-oil your air filter with a K&N air filter cleaning kit, returning it to like-new condition. Your one K&N air filter is designed to last for the lifetime of your vehicle, which K&N guarantees will perform for up to 10 years or 1,000,000 miles without requiring replacement. For full details visit the K&N Million Mile Limited Warranty.

You can order the filter simply by using the part number 33-2104 as well as order the cleaning kit 99-5000.

For all K&N air filters that fit the Honda Civic, visit Honda Civic air filters. To find additional K&N upgrades for cars, trucks, scooters, motorcycles, motorhomes, or almost anything with an engine, use the K&N Search by Vehicle tool. Find an authorized K&N dealer nearby using the K&N Dealer Search.

The 33-2104 replacement air filter fits the following vehicles:

2016 Sturgis Motorcycle Rally Shows Off New K&N Air Intake Systems for Harleys®

new intake systems for 2001-2015 Harley-Davidson Softails and Dynas and 2008-2016 H-D Touring models

The new intake systems for 2001-2015 Harley-Davidson Softails and Dynas and 2008-2016 H-D Touring models feature a black textured finish, large air filter, cast aluminum air tube with integrated velocity stack and breather system.

K&N has been hard at work developing, engineering, and producing the next innovation to hit the motorcycle world, a performance-oriented intake system for various 2001-2016 Harley-Davidson® models. The new kits will boost power and torque by increasing airflow into your V-Twin while also providing exceptional filtration qualities to help protect your investment.

new intake systems for 2001-2015 Harley-Davidson Softails and Dynas and 2008-2016 H-D Touring models

The 63-1137 and 63-1134 kits include everything needed to install the kit in around 90 minutes or less.

Expanding on our ever popular AirCharger motorcycle air intake systems, the new AirCharger intake system is built with a high-velocity, cast aluminum intake tube that directs airflow into a built-in velocity stack with completely integrated breather system. An oversized, oiled cotton, clamp-on air filter feeds air directly into a wide air tube with an integrated velocity stack for enhanced airflow characteristics. The systems also feature a brushed aluminum K&N logo with a contrasting black textured finish. This design will stand the test of time no matter what trends come and go. Both kits also feature completely integrated breather systems, so they are a direct replacement for the stock system on your bike.

new intake systems for 2001-2015 Harley-Davidson Softails and Dynas and 2008-2016 H-D Touring models

Once installed on your bike, both new AirCharger systems look great while also boosting horsepower and torque, increasing airflow, and protecting your V-Twin engine from harmful contaminants.

Because K&N's primary motivation for building these intake systems, is providing you with more horsepower to the rear wheels, K&N provides a guarantee to increase horsepower. On their in-house dyno, K&N saw an estimated 6 horsepower and 6.5 lb-ft of torque gain for the 63-1134 kit on a 2016 H-D Street Glide. The 63-1137 system made an estimated 5 horsepower and 8 lb-ft of torque on a 2016 Harley® Switchback. These power numbers are achieved using technology that K&N pioneered on their car and truck intake systems. Now, using cast aluminum, K&N is able to precisely direct the airflow to limit restrictions and promote smooth, laminar flow and increase airflow velocity.

The K&N 63-1137 is developed to bolt directly onto your 2001-2015 fuel-injected Harley Softail and Dyna, while the 63-1134 fits 2008-2016 Harley Touring models. The installation process is extremely easy and usually takes 90 minutes or less. When it comes time for maintenance, use the K&N 99-5000 air filter ReCharge kit. Complete with K&N PowerKleen cleaning solution to remove the dirt, road grime, and bugs from your filter and K&N filter oil to re-oil it and get you going down the highway.

For more information on this kit and everything else K&N makes, visit knfilters.com and use the Search by Vehicle tool to find the right product for your car, truck, motorcycle, lawnmower, or just about anything else with an internal combustion engine. If you are going to be in Sturgis for the motorcycle rally, be sure to stop by Black Hills Harley-Davidson, J&P Cycles-Sturgis, or Cycle Solutions to check out these new kits in person. Also, stop in to see us in Rapid City, South Dakota for the 76th annual Sturgis Rally located in the Black Hills Harley-Davidson vendor lot from Aug 5th through august 14th.

Not legal for sale or use on any pollution controlled motor vehicle in California or states adopting California emission procedures. See knfilters.com for CARB status on each part for a specific vehicle.

Kyle Leduc Returns to Lucas Oil Off Road Series Round 9 and 10 at Glen Helen Raceway

Kyle LeDuc Pro4 race truck

K&N sponsored driver, Kyle LeDuc's Pro4 race truck getting the once over after qualifying. Kyle jumped in to fix a little wiring.

Racing is a passion that can consume you. It requires more than just a dream, it requires dedication. Whether you are the occasional amateur racer or a member of the professional elite, the commitment is the same. And to excel in this sport takes a very special individual with a very special support system. Kyle LeDuc seems to be a very special individual. You might say Kyle's been racing all his life. Whether it was RC cars or bicycles behind dad, Curt LeDuc's Race Shop, he and his brother, Todd, were quite possibly born to be fast! While dad was in the shop building race trucks, Kyle and Todd, were building jumps in back for their RC cars, and riding bikes together almost every day. The boys need for speed eventually led them to winning championships racing downhill mountain bikes. Clearly they were natural's. As the boys got a little older Todd stayed the course of downhill racing, while Kyle chose to follow in his father's footsteps.

Kyle spent many a weekend out at the track with his dad as his spotter. He told K&N that he tried to encourage his dad to try different lines, angles that he'd seen the other drivers taking on the track that gave those drivers an edge. After a while Kyle told his dad he wanted to race. He wanted to see if his "sideline driving" from the spotter's station was enough to compete and win. His dad's response went something like, "Well you better build yourself a truck." It seems the rule in the Leduc family is "if you want to race it, you have to build it".

And so it began.

Mike Hamrick of Wilwood Disc Brakes stopped by the pits after the race to congratulate Kyle.

Anyone who has attended a short course race in the last decade or so is familiar with the Leduc name and Kyle's accomplishments on the track. LeDuc is a threat to win anytime gets behind the wheel on the track. Kyle entered his first off road race in 2002 at the tender age of 20 where he spent that year testing and tuning, learning the mud and the line and what he needed to know to become the best driver he could be. In 2003, Kyle took the title of Prolite World Champion at Crandon International Raceway. This would be the first of many more wins to come. Back then "The Kid" was the youngest driver at these tracks pulling times just as aggressive as some of the off road legends. In 2004, Kyle's second full year of racing, he earned the title of Prolite Champion. The hard work and dedication to his passion was beginning to pay off.

As with most competitive racers, there comes a time when you want more. For Kyle that was in 2008 when he made the switch to Pro4 category. It didn't take him long to adjust from a 2-wheel drive race truck to a 4-wheel drive as evidenced by earning his first win in that first year! In Pro4 LeDuc was a force to be reckoned with earning countless podiums and wins. However, 2012 proved to be a most memorable year. Something Kyle had been working toward tirelessly became a reality. Kyle earned the title as Pro4 Champion. It was at that moment he recognized that his hard work, dedication and commitment, ten years in the making, paid off and he was crowned Off Road Pro4 Champion.

Not only is Kyle one of the off road world's most influential and successful competitors, he is a hardworking, dedicated family man. He is kind, generous with his time and LOVES this sport. It isn't a hobby for him, it's his career. And for that he is incredibly proud. Growing up around his father's fabrication shop taught him what was needed to build a competitive truck. He works on his own race truck telling us in doing so he knows what will work for him. He has the mind of an engineer and knows how to use his hands and how things work. The connection of man and machine gives him an edge. It's clear that he appreciates the other driver's and teams that he competes with as well. They drive him to up his game always, in all ways. Kyle's not just the Pro4 Race Truck driver, he's the mechanic, the set-up guy, the office staff, the janitor. He kind of does it all. Yes, he has a crew and people that he relies upon for help. But for him it's important to stay connected. And at the end of the day, he's not taking a private jet home, not sitting in a luxury bus with the A/C on while everyone else caters to his every whim. He's the guy.

White flag lap, turn 3, Kyle drops down on the inside of Carl to take the lead!

The 2016 Lucas Oil Off Road Series season started off a little rough for our #99. While practice and qualifying was always stellar it seemed Kyle was plagued by mechanical issues that would prevent him from not just winning a race, but in some instances rendering him unable to complete or even start the race. In Round 1 & 2 at Wild Horse Pass he had a power steering burst that caused a fire during Saturday's main event and mechanical failure with the 4-wheel drive prevented him from making it through turn one on Sunday. At Lake Elsinore for Round 3 & 4, more of the same. Great practice and qualifying times with more mechanical issues in the main events. Kyle's luck would begin to improve in Round 5 & 6 at Utah Motorsports Campus. He would finish 4th on Saturday and sweep the competition on Sunday earning his first win of the season.

With all the mechanical issues behind him, LeDuc would go on to Ensenada, Baja California, MX, to compete on the beach sand of the Estero Beach Resort for Round 7 & 8, where he would once again be back on the podium earning a third place finish on Saturday and a first place finish on Sunday. Once again LeDuc was proving that yes he was a force to be reckoned with and that more over - he was back!

The Lucas Oil Off Road Series returned to the US for Round 9 & 10 that took place at Glen Helen Raceway, CA on July 23rd and 24th. Southern California was literally a blaze with the massive Sand Fire which would go on to burn more than 60 square miles in the Santa Clarita area. The temperatures were well in to the triple digits, but that didn't stop our racers or fans from taking part in the excitement. Opening ceremonies on Saturday at Glen Helen included a bittersweet remembrance to the "14" victims killed in last December's terror attack in San Bernardino. Bob Patison, president of the Corona Based Lucas Oil said, "We wanted to do something for the survivors to honor the victims of this terrible event." And Lucas Oil Off Road Series along with 14 drivers did just that. The names of the 14 people who perished were displayed on fourteen driver's vehicles. As well, a number of the "First Responders" to the scene were on hand to participate in the ceremony. After a moment of silence and prayer, the fan's gave San Bernardino's finest a standing ovation for their commitment and courage. You could feel a deep sense of gratitude from everyone in the stands as the crowd cheered. But now it was time to do a little racing.

Kyle LeDuc 1st place finish on Saturday and Sunday at Round 9 & 10 of the Lucas Oil Off Road Series at Glen Helen Raceway

Congrats to Kyle LeDuc on his 1st place finish on Saturday and Sunday at Round 9 & 10 of the Lucas Oil Off Road Series at Glen Helen Raceway.

The weekend was riddled with distractions but our #99 didn't miss a beat. He was most assuredly back on his game, relaxed and ready, with the mechanical issues that had proved problematic early on in the season, now by the wayside. Kyle was consistently laying down fast lap times during practice. He was seriously in the zone. In qualifying we saw the same thing. LeDuc was eating up the competition, qualifying second on Saturday and first on Sunday. His mark? Carl Renezeder. Those two would put on the best show of the season thus far in Saturday's Pro4 Main Event. With an early caution bunching up the field, LeDuc could stay right on Renezeder's rear end, lap after lap. Multiple yellow flags would continue to wreak havoc on the field, not to mention the track itself. Just when Renezeder would increase the gap between him and LeDuc, the off road Gods seemed to say, "Not today Carl, not today!" and Kyle would be right back on his tail!

As the white flag dropped with Kyle still trailing by a half a truck length, this race turned in to a real nail biter. Everyone in the stands was on their feet. Anywhere it seemed Kyle could pass, Carl shut him down. The crowd was literally going wild. And then it happened in turn 3. Kyle LeDuc snuck passed Carl Renezeder and started to pull away. With just a few whoops, a few jumps and a few turns to go, LeDuc had everyone's attention. But no matter how hard Carl charged, Kyle charged harder ultimately winning Round 9 on the last lap. Carl would come in a close second with Doug Fontin coming in third. After the excitement of Saturday's main, we are proud to report that Sunday went even better! The competitors saw fewer caution flags and a second or two quicker lap times. LeDuc won the main event having led the entire 16 laps, with Renezeder a close second and Menzies rounding out the podium with third.

Lucas Off Road Racing Series will descend upon Wild Horse Motorsports Park in Spark, NV for more intense wheel to wheel racing on August 13th & 14th. K&N wants to congratulate K&N Race Team Driver Kyle LeDuc for his incredible success at Glen Helen Raceway this last weekend and look forward to seeing LeDuc wheel his Monster Energy Ford Pro4 Race Truck to another epic victory next month.

BMW 6-Cylinder Models with Air Filter Change Can See Further Efficiency and Airflow Improvements

K&N air filter for BMW

K&N filters are both computer-designed as well as hand-tested on sample BMWs to make certain the purchasers get an OEM level of fit.

If you were to select one type of product produced by the Bayerische Motor Werke (BMW) to hold up as an example of their engineering prowess, it would have to be their inline six cylinder engines.

While much of the rest of the automotive worlds has abandoned the inline six for the more compact (especially for front-wheel drive applications) for some version of a V6, BMW has held tight to its commitment to the smoother-running straight six that requires no balance shafts or unusual timing needed to calm the otherwise rough-running V6 configuration. In fact, BMW has been experimenting with V6 designs for a number of year but are never able to get one to meet corporate noise and harshness standards.

While over the course of nine years, BMW has developed and replaced its six-cylinder designs, they have relied upon the same basic air box configuration, into which the K&N 33-2292 air filter is the perfect fit.

The first applications for the K&N 33-2292 began in 2003 with the BMW 520i, 525i, and 530i, which were fitted with BMW's M54 is a straight-six DOHC engine. The M54 uses an aluminum block with cast iron liners and an aluminum cylinder head with cast iron cylinder liners. Further, the M54 features variable valve timing to both camshafts (dual VANOS in BMW speak) and a dual length intake manifold, which was named DISA by BMW.

K&N air filter installed into  BMW

Underhood there's no sign that you've made a performance upgrade to your BMW six-cylinder engine.

The final application for this long-lived air filter design was the 2010 and 2011 BMW 630i. Despite the passing of eight years, the filter configuration, available as K&N 33-2292, remained the same even though the N52 engine was quite different.

Like the BMW M54, the BMW N52 is a straight-six DOHC engine. Compared with its M54 predecessor, the N52 features variable valve lift (ingeniously named Valvetronic by BMW), a lighter magnesium engine block and an electric water pump and a variable speed oil pump. Like the M54, the N52 uses an electronic throttle control, the VANOS variable valve timing to both camshafts and the dual length DISA intake manifold.

These are just the bookends of the applications for this filter. In between are cars as diverse as the Z4 and models of the 3, 5, and 7 Series.

Regardless of whether your BMW is powered by a 2.0 L, 2.5 L or 3.0 L engine, installing a K&N filter provides an increase of up to 50% incremental air flow to the engine. By increasing the flow of air, it can result in a more responsive throttle and improved torque at all points of your BMW's operating range.

K&N air filters are assembled from several layers of oiled cotton filter media, which accounts for their long service life. Also the oiled cotton medium allows for increased air flow as well as offers excellent filtration characteristics. Often OEM and less-expensive filters are made from more restrictive paper media which can actually limit the output potential of the engine. The performance of each filter design is verified through K&N's in-house efficiency testing, which follows strict ISO 5011 standards, and confirms that K&N filters provide a high volume of intake airflow without sacrificing engine longevity.

And once you've installed your K&N 33-2292 air filter you've eliminated the need to purchase and replace paper filters for the life of your six-cylinder BMW 3, 5, 6, 7, and Z4 series. The only maintenance necessary is one you can do yourself in just a short time. At intervals of 50,000 miles or about 80,000 kilometers (depending on your driving conditions) simply use a K&N air filter cleaning kit to easily clean and re-oil your air filter -- returning it to like-new performance levels. Your one K&N air filter is designed to last the lifetime of your vehicle, which K&N guarantees will perform for up to 10 years or 1,000,000 miles without requiring replacement. For full details visit the K&N Million Mile Limited Warranty.

You can order the filter simply by using the part number 33-2292 and while you're at it, grab an air filter cleaning kit, part number 99-5000.
