Testing the K&N BM-1113 Air Filter for the BMW R1200GS in the Death Valley Dirt

The R1200GS on a Death Valley dirt road

Death Valley is a prime testing environment for an air filter

The 12,000-mile service on the new liquid cooled BMW R1200GS is a big one. It’s the maintenance milestone that requires a valve check/adjustment, spark plug replacement, engine and drive oil change, various system checks, and an air filter replacement. That final one is the focus of this piece.

I have used K&N oil filters for years because I trust the quality, and I appreciate the 17mm nut on the filter body for easy replacement. I have also used a full range of K&N air filters on my street-only performance motorcycles. However, the GS is an adventure (ADV) bike that I ride in a full spectrum of conditions over a variety of surfaces including dirt. I have been wary of using anything but the stock paper filters in the air-boxes of any of my adventure mounts (I have owned nearly a dozen ADV motorcycles of various brands).

K&N BM-1113 and stock filter side-by-side

A side-by-side comparison of the filters emphasizes the K&N's build quality

As is my modus operandi, I did careful research on the K&N air filters that are intended for dual-sport duty. I studied K&N’s filtration testing protocols and the resulting test data. I considered the ways K&N’s engineers added extra layers of tightly-woven cotton gauze filter media for the more demanding duty of adventure riding. I noted the filter body’s sealing bead and overall construction. In the end, I felt fully confident that K&N had developed a filter element that would add a higher level of airflow to the GS’s big cylinders, while still providing excellent filtration to protect the engine.

Comparing the K&N BM-1113 alongside the stock paper filter, the K&N’s build quality and well-designed sealing surface are notable. It has a more rigid body than the stock filter element, but the sealing surface is pliable making for a reassuring fit into the GS air box. The K&N filter fits perfectly into the air box’s support frame and seals up well when the lid’s four bolts are torqued into place. Of course, the final step in the easy and quick installation is the application of the K&N “do not discard” sticker on the air box cover.

So with the 12,000 mile service complete, including the installation of the K&N BM-1113, it was time for an adventure. The filter’s first ride would be a 1000-mile journey that would include an exploration of Death Valley, including miles of the region's dirt roads. Since Death Valley boasts the lowest point in the United States, the filter’s performance in low elevations would be tested. The ride would also include an extended high-speed freeway leg, and finally a twisty climb into 9000 foot elevation of Arizona’s San Francisco Peaks. That is clearly a viable real-world test of a filter’s performance.

So how did the filter perform? On the road, my seat-of-the-pants conclusion was that the filter’s airflow smoothed out the bike’s annoying hesitation when accelerating from about 4000 RPM. The roll-on performance was smoother and stronger. Yes, I know it is only seat-of-the-pants testing, but I will tell you that my seat spends countless hours and miles in the saddle, so I get to know my bike very well. I will vouch for the noticeable improvement in mid-range performance on the GS.

ADV bikes have multi-surface capability which requires effective filtration

As far as my overall performance impressions, they too are very favorable. The ride included an elevation change of over 9000 feet. The bike performed flawlessly at the negative 282 foot elevation of Death Valley and the heights of the northern Arizona mountains. An especially notable performance boost was the crispness of the bike’s throttle response at the highest elevations. Clearly the added airflow helped in the thin mountain air.

Upon returning home, I removed the K&N from the air box for a post ride inspection. The filter’s seal was secure and the element looked perfect. Of course the air box was spotless. I have no reservations about running the K&N BM-1113 for the next 100,000 miles that I expect to keep the big GS. I am also more than pleased that I can wash and re-oil the filter after a particularly dirty ride, rather that trash a paper filter. This adventure rider is now a convert.

K&N Racing Assembly Combines Durable Construction With Superior Performance

The K&N 100-8593 Custom Racing Assembly.

The K&N 100-8593 custom racing assembly offers maximum airflow for greater horsepower.

Racers are always looking for something that gives them the edge over their competition and the K&N 100-8593 custom racing assembly is one component that assists.

It includes an air box constructed of ultralight and durable K&N generation 2 carbon fiber that is durable enough to take the extreme vibrations and engine heat that always results from achieving maximum speed. Yet, as it withstands the upheaval it delivers superior airflow and is designed to increase horsepower. The rectangular air filter features multiple layers of cotton gauze media, which has been treated with a special grade of filter oil that make the strands of the cotton extremely sticky.

The air box has air horn seals for better insulation and easy installation. It is ideal for racers who drive racecars that use traditional multi-Siamese stacks.

It’s no accident that K&N uses carbon fiber in the construction of the assembly. The composite has been treated to deal with extreme heat from less than 0° up to 2500° Fahrenheit and is engineered with specific resin systems for application specific needs. To work properly there has to be a balance of fire retardant resins and ceramic blends so the component can withstand the intense heat and yet be flexible enough to avoid damage.

English Legends Champ Heads to the U.S. to Recapture His World Crown

The bright orange Mickel Motorsports entry is hard to miss on UK circuits

Forget about British reserve, this car can be spotted from the International Space Station

As strange as it seems, as you’re reading this there’s a team from Great Britain traveling to the American South to race scale replicas of dirt track stock cars of the 1950s and 1960s bodied in the shells of two-door coupes and four-door sedans of the 1930s.

The story actually starts in 1992, when many short tracks had allowed the cost of competition to escalate out of control with variable and sometimes unclear rules. Car counts began to drop drastically, and at that moment, track officials estimate that 30% to 40% of the racecars in North America were not in use because of cost.

What was needed was an affordable racecar that required little maintenance time and cost. Recognizing the need was the team at Charlotte Motor Speedway, who researched the problem. As a result of this research, in January 1992, US Legend Cars International, Inc. was launched and in April of 1992, the first Legends Car was unveiled. Currently they are the largest mass producer of racecars in the world.

John Mickel is 2015 and 2016 UK Legends Champion

UK Champion John Mickel heads to the US to defend his World title

While the intention was for Legend cars to compete on short paved and dirt ovals, they started appearing in other situations. You can find them today running on race tracks with NASA, SCCA, and other groups. And they’ve spread across the globe as well. In Finland they’re raced on road courses in the summer and on frozen lakes in the winter. In addition to the UK, where our friends are from, there have also been series in France, Mexico, Belgium, Spain, and Australia.

In most of the countries, an infrastructure of paved or dirt ovals doesn’t exist, so the Legends cars are raced on road courses. In the UK, there are 15 rounds held on tracks that hosted Formula 1 races like Silverstone, Brands Hatch, and Donington Park are on the schedule as well as club circuits likes Pembrey and Anglesey.

Three races are held – two heats and a final – at each round of the championship, with the heats lasting between 7 and 12 laps depending on the circuit, with the final a few laps longer. The grid for race one is drawn by lots, with the reverse for heat two, and in the final the grid is formed by the reverse of the drivers points in the previous two races – meaning the most successful driver will start near the back. In each race, however, all rookies start at the back of the grid.

K&N filters improve the performance of the Yamaha engines used by all Legends cars

You can catch a glimpse of a pair of K&N RC-3510 air filters under the hood

This year’s UK champion is John Mickel who took the 2015 championship as well. “I'm really pleased to win it again especially as winning last year makes it back to back titles. Every year it gets harder. My 19 years of experience in Legends Cars keeps me fighting at the front and of course using the best equipment like K&N Filters helps.

John is bringing his winning number 4 K-Seal Legend car to the States, to be defending his world title and he’s excited to be doing so. “The USA is where the Legends cars were designed and first raced," he said. “It's like bringing the car home. Racing against the best of the best from each state of the USA plus drivers from Russia, Georgia, Sweden, Finland and winning both the World Title and the World Points Series last year, I just had to come back and defend them both in 2016.”

John’s no newbie to racing in the US. He spent several years trying to put together a NASCAR truck program, budget limiting him to running only a handful of races each year. So he turned his focus back on the UK and dominated ever since.

So how does a car from the UK compete with a car from the US or Russia or Finland? Machinery is kept evenly matched around the globe by all chassis and components manufactured only by US Legend Cars International, Inc. In addition every car is powered by a sealed Yamaha engine. With so much controlled by the organizers, small allowed differences can make a big difference. According to John, “engine costs are a big part of our budget, and using the best equipment available has always been cost effective. That’s why I have used K&N air and oil filters for over 30 years, because they’ve never let me down.” Just for the record, each car in John's stable is equipped with a pair of K&N RC-3510 filters.

While our focus has been on John as he heads for the World Championships, there are other members of his team that have plenty to celebrate themselves. Paul Simmons was crowned the 2016 UK National Masters (over 40) Champion in his black #51 Baileigh Industrial-sponsorsed machine, while the #3 K-Seal car shared by Mike Schlup and John Patterson won the 2016 UK Team Car National Championship title.

2016 Acura ILX Air Intake System Offers an Estimated Boost of Six Horsepower

K&N 69-1503TS Air Intake reduces airflow restrictions and boosts horsepower.

The K&N 69-1503TS air intake under the hood of an Acura ILX.

Founded on March 27, 1986, Acura is the luxury vehicle marque of the Japanese automaker Honda. Its cars are available all over the world first appearing in the United States and Canada in 1986, introduced to Hong Kong in 1991, Mexico in 2004, China in 2006, Russia in 2014, and Kuwait in 2015. It is the first Japanese automotive luxury brand.

Early in its existence, Acura became a major best-selling marques in the United States. The company introduced its first flagship vehicle, the Legend, in the 1980s. The car was so successful it inspired fellow Japanese carmakers Toyota to start its luxury marque Lexus and Nissan to launch its luxury division Infiniti.

When Acura debuted the NSX mid-engine sports car in 1990, it offered one of the most reliable and practical alternatives to exotic European sports cars at the time.

Despite starting well, Acura experienced a sales decline in the mid-to-late 1990s. Critics blamed the drop on less inspiring designs. In addition, the parent company, Honda, suffered as the result of an economic decline in Japan during the 1990s and 2000s.

The company rebounded with the introduction of a number of new models between the years 2000 and 2003. This is when the Acura TL sedan, the RSX sedan, and the MDX crossover SUV were unveiled.

Between the years 2004 and 2006, the car manufacturer released four more new models - a brand new TL, the RL, TSX, and RDX. A new V6 engine that delivered 270-horsepower helped to galvanize interest in the TL, which experienced a dramatic sales increase in the United States to 70,943 units over the previous model in 2005. A V6 engine that produced 300-horsepower powered the newly introduced RL that also included an All-Wheel Drive system that was capable of sending almost all of the power to just one wheel in a turn. The RL landed on Car and Driver's 10 Best List in 2005 and CNET.com awarded it "Editor's Choice" that year. Automotive journalists raved about Acura's new models. For example, Car and Driver named the TSX to its 10 Best list from 2004-2006.

Between the years 2007 and 2015, Acura introduced six more models - the ILX, TLX, RLX, RDX, MDX, AND ZDX.

K&N offers the 69-1503TS air intake kit for the 2016 Acura ILX. Estimated to provide a boost of 6.37-horsepower at 6069 rpm, the system includes a free-flowing mandrel-bent aluminum tube, four stainless steel clamps, and K&N RC-5138 chrome topped round tapered air filter that features a multi-layered cotton gauze media treated with a special grade of filter oil. The oil saturates the cotton strands making them tacky and thus capable of capturing and holding contaminants. The air filter is also washable and reusable and performs for 100,000 miles of continuous use until cleaning is required, depending on driving conditions.

The K&N 69-1503TS Air Intake for the 2016 Acura ILX.

The K&N 69-1503TS air intake includes the K&N RC5138 air filter.

K&N also offers an air filter cleaning kit, 99-5000 that can be used to cleanse and recharge the filter so that it can be reused over and over again.

K&N is so sure of the quality of the air filter it backs it with a 10-Year/Million Mile Limited Warranty®. The company promises that the filter will perform for up to 10 years or 1,000,000 miles without needing replacement.

The air intake is designed to dramatically reduce restrictions as it smooths and straightens airflow allowing the engine to gulp more air than the factory air intake provided. A heat shield is present to prevent hot engine air from entering the intake. The entire system is designed to fit into the original factory air box space.

The air intake system can be installed using the existing factory mounting points and common hand tools in about 90 minutes.

The K&N 69-1503TS air intake system is designed to fit the following vehicle applications:

Haaker Tops Webb in a Rough-and-Tumble EnduroCross Stage 7 in Idaho

The seesaw battle between Cody Webb and Colton Haaker has emerged as the exciting storyline of the K&N-sponsored 2016 Professional EnduroCross season. This week in the Ford Idaho Center in Boise, it was Haaker’s turn to grace the top podium spot with Webb following to a second place finish. The duo won their respective heat races and Haaker again reaped the gate-selection and bonus-point rewards by winning the Hot Lap.

The main event was chock-full of the spills and chills that are the earmarks of the sport of EnduroCross. Haaker garnered the Holeshot to start the race. Conversely, Webb’s first lap was treacherous as he went down hard and collected the tire marks of several riders as they rolled over him. He gathered himself and reentered the race well back of the pack.

Haaker lost the lead on lap 2 when he got stuck in the firewood section. He was passed by two riders, one of whom was the eventual third place finisher, Kyle Redmond. As Haaker continued to struggle with the firewood pit several times throughout the race, Webb steadily reeled in riders to regain a position near the front of the pack. Haaker said, “I got the Holeshot and was riding really good but got stuck the first six laps.” He was fully aware of Webb’s problems in keeping his KTM upright, but admitted the firewood got the best of him. “I saw Cody crash several times and he was going down hard and still managed to catch me because I was getting stuck in the firewood.” In the end, Haaker showed why he is the series points leader by fighting through adversity for the win.

Podium finishers in Idaho

Webb’s second place finish was the result of pure determination. He had thoughts of throwing in the towel after being run over on the first lap. “In the beginning I almost wasn’t going to keep going. I took a big digger and got run over but I realized I was not seriously hurt.” His trials and tribulations didn’t stop there. “Then I crashed again from the top of the rock pile so my bars were bent, but I gave it my all to get back up there.” Webb’s toughness was rewarded with the podium finish that keeps him in the championship hunt. Webb now trails Haaker by 14 points after the Idaho race.

The final weekend of the EnduroCross season will be a two-day event staged at Citizens Business Bank Arena in Ontario, CA. The November 18-19 race will decide the 2016 EnduroCross Championship, and figures to be a raucous event.
