Since 1969 K&N Engineering has been designing, manufacturing, and enhancing High-Flow Air Filters for the automotive and motorcycle enthusiast interested in maximizing horsepower and acceleration.  Since our humble beginnings we have designed and manufactured over 2,400 High-Flow Air Filters to fit most modern passenger vehicles and over 500 High-Flow Air Intake Systems to fit vehicles driven by enthusiast minded drivers.  We not only have more applications than any other manufacturer of similar product, we invented the High-Flow category and the High-Flow Technology that supports it.  K&N also makes thousands of racing and specialty type air filters and is the #1 Filter in NASCAR?.

K&N Motorcycle Racing
The K&N FilterCharger? air filter is designed to achieve high, virtually unrestricted air flow while maintaining filtration levels critical to ensure long engine life.  Our automotive OE (original equipment) replacement air filters generally add 1-4 horsepower. The secret to our success lies in the unique characteristics of our air filter medium that was originally developed by K&N all those years ago in the dust, sweat and tears of desert motocross racing.  We just wanted to win races and stumbled on a cotton filtration technology destined to be great.  Our high flow cotton gauze air filter is washable, reusable and built to last for the life of an automotive or motorcycle engine.  K&N air filters consist of four to six sheets of cotton gauze layered between two sheets of aluminum wire mesh.  This media is then pleated and oiled to enhance its filtering capabilities and overall performance.  K&N Air Filters were created for an environment requiring maximum horsepower and enhanced acceleration in addition to protection from the dirt and dust of off-road racing.  The result is an air filter that allows dramatically more air into an engine, is washable and reusable, and will protect your engine for the life of your vehicle.

Engine Protection, Filtration
Anyone can flow more air.  The trick is to flow more air safely.  In our opinion we hit the sweet spot _ an optimal blend of high air flow, filtration efficiency, durability and dust capacity.  We take filtration seriously.  K&N Air Filter media has been tested both in-house and by independent labs using the ISO5011 test developed by the Society of Automotive Engineers.  In addition we test many of our filters both in and out of the OE airbox ensuring proper fit and function.  Our goal is to design filters with the maximum possible airflow achievable while providing guaranteed engine protection.
The Importance of Oil
A K&N Air Filter is made of 4 to 6 layers of cotton gauze sandwiched between two epoxy-coated aluminum wire screens.  The cotton is treated with a specially formulated grade of oil causing tackiness throughout the cottonÉs microscopic strands.  The nature of the cotton allows high volumes of airflow, and when combined with the tackiness of the oil creates a powerful filtering media that ensures engine protection.  In contrast, most other media can not maintain the same balance of airflow and filtration throughout the filter's life without sacrificing one or the other.  With a K&N Air Filter, there is no sacrifice.

Testing _ Laboratory and Real World
K&N uses independent laboratories to help ensure that our products meet or exceed your high performance and high filtration demands.  Better yet, we conduct our own testing at our own state-of-the-art in-house testing laboratory.  For more information on K&N air filters and testing go to the K&N Technical Learning Center area.  K&NÉs dedication to providing a first-class air filter can also be seen outside the testing laboratory. Consider that K&N has sold more than 20 million air filters since 1969. One such filter was put in the airbox of a three-quarter ton Chevy pickup and driven more than one million miles by Carl Judice of New Iberia, Louisiana. Carl points out that he has never rebuilt the engine, nor removed the cylinder head from his trusty pickup truck. Real world testing and customer satisfaction doesnÉt get any better than that.

Never Replace Your Air Filter Again
Handmade in the USA and in the United Kingdom using only the finest materials, K&N OE Replacement Air Filters are washable and reusable.  Regardless of what youÉve heard, itÉs almost impossible to wash your K&N Air Filter too much.  Inside our testing laboratory, we have washed and re-oiled one K&N Air Filter more than 100 times and it still performs up to specification.  Depending on your driving conditions, we recommend cleaning your air filter every 50,000 miles.  To clean and re-oil, purchase our filter Recharger? service kit and follow the easy instructions.

Fuel Economy
Fuel economy testing and mileage claims are a tricky business. Just ask the EPA, whose website states, "EPAÉs fuel economy estimates are designed to allow consumers to comparison shop.  Your fuel economy will almost certainly vary from EPAÉs fuel economy rating.  This is based on a number of factors, such as weather, road conditions, your driving and maintenance habits, and your use of air conditioning."  A lot of exaggerated claims are made in the marketplace by products claiming to improve gas mileage.  K&N makes no general fuel economy claims, however we encourage you to try our air filter for yourself.  Keeping air filter restriction as low as possible can be an important tool, among others, for maintaining high mileage.

K&N Million Mile Limited Warranty? and Consumer Protection Pledge
K&N warrants its street vehicle OE Replacement Air Filters for one million miles. When used properly and found to be defective, return your filter and the receipt from purchase and K&N will replace it free of charge. K&NÉs Consumer Protection Plan goes one step further than its Million Mile Warranty. The performance aftermarket has, at times, been plagued by car manufacturers and automotive dealers that may attempt to discourage you from customizing your vehicle. They prefer you buy OE parts and not modify your car or truck and have even been known to void their own manufacturerÉs warranty due to vehicle modification. That sounds un-American to us, which is why K&N and the Magnuson-Moss Warranty Act protect consumers from such denied warranty claims.  When you buy an OE replacement K&N High-Flow Air Filter or High-Flow Air Intake System you can be confident your vehicleÉs warranty will remain in effect.  If you experience a difficult dealership, K&N will resolve the issue so you wonÉt have to. The following summarizes the K&N Consumer Protection Pledge:

K&N pledges to our customers that they will not be taken advantage of and charged for a repair due to a dealership warranty denial blamed on the presence of a K&N product..

We believe K&N makes The WorldÉs Best Air Filter and we stand behind that claim 100 percent.

"Very user friendly website. Much better than others. Customer service is also excellent."

"I purchased a set of endless ss-m brake pads for my mr-s, and it was exactly what I needed for my desired set up. Vivid Racing was generally the first online store I found that actually offered a cheaper price if you bought a whole set, rather than to individually buy a front pair and a rear pair of these brake pads. I was more than satisfied with the price of the whole set, and was extremely happy when I finally got them on my car. Thank you Vivid Racing."

"I drive a 2009 e92 M3. It was completely stock, and ran the 19" RE-11s. A few months ago, I started tracking the car at Thunderhill and Laguna Seca. The first day, I realized that stock pads performed poorly, so I upgraded to Carbotech XP-10s. At my second track day, wore the Carbotech pads down to the rivets, and got the brakes so hot that I actually melted a brake line where it attaches to the front caliper. After putting ss lines on, I upgraded to the XP-12s. I was to try them out my first go at Laguna weekend event. The first day was great--really loved the performance. But I noticed early the second day that the pads were toast, down to the rivets. The RE-11s were wearing (they have about 30K miles on them), and I wanted to upgrade to an R-compound tire. Not too many options for 19s, so I opted for the 18" Volk Racing TE37SLs, and went 9.5 and 10.5, with +22mm and +20mm offsets. I paired them up with Toyo Proxes R888s, with 265/35/18 97Y RD in the front and 295/30/18 98Y RD in the rear. The wheels and tires fit the car without any problem or mods (no cutting)--indeed, I probably could have gone 305s. I also upgraded to Pagid 19s (tho I left the Carbotech XP-12s on the rear). I tried everything out at Thunderhill last weekend. There was a lot of rain, and so both mornings were very wet--and slick on the new tires. But the afternoons were ideal, especially Sunday. I still need to work on dialing in the tire pressures, but the grip was phenominal, especially on the wide sweepers (Turn 2 and Turn 3). I could easily handle Turn 2 in 4th gear, and there seemed to be no end to the lateral grip. Harry's Lap Timer was measuring well beyond 1.0 g in that corner. More importantly, the car felt very balanced. I only experienced a tiny bit of oversteer in Turn 11, but that is because the track was green and I was very early onto the power. The Pagids seemed to wear much better than the Carbotechs (I was able to drive two days without getting into the rivets), but they don't have the same feel. I tend to brake pretty hard, and the M3 is a very heavy car. It seemed like the brakes weren't frequently at the right temp--either too hot or too cold, and thus warranted less confidence. Part of this was due to the track/weather conditions. But there were a couple of times coming hard down the back straight into Turn 14 where I wondered if the car would slow enough for the turn. I probably need to put Pagids on the rear, and hit the track again. The guys at Vivid really took care of me, especially Ahmed. Since all of this is new to me, I have a million questions. He was always very responsive and provided me with the information I needed to make the right decisions. I am really happy with the entire setup, and would recommend Vivid without hesitation."
