Product Description
The Original High-Flow Air Filter. 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 only air filter used at the Indianapolis 500 Race®. 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 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 vehicle.

Customer Reviews
Highly recommended
I bought two of these filters for my 2000 Mazda MPV (6 cylinder) and 2002 Honda Accord VP (4 cylinder) (the filter here is for Honda). Let me state the most important result first: both cars improved the MPG. To be specific, the MPG improvement in the city is 17 to 20 and 20 to 22 in Mazda and Honda, respectively. I have used the air filters for over a month now and each car went through at least two tanks of fuel, actually Mazda spent four tanks due to a three-day trip. So, I can say that these are fairly accurate measurements. I must also state that I always keep my cars well maintained; my engines are tuned, oil changed, injector cleaned, etc. regularly. Additionally, I would still buy the filters without any MPG improvement, because the engines are running much smoother now. I especially feel the improvement at low RPM, definitely pressing the gas pedal less to accelerate and maintain the speed. Both engines are idling smoother at a slightly lower rpm. I heard critics for these filters about letting too much dust in the engine, and I was worried about this as well. But, as I said earlier, both engines are running smoother now; they are definitely not complaining. I think, as long as I do not neglect changing oil in regular intervals, there should be no problem. And, I have been doing that anyway. I highly recommend these filters if you are following the regular engine maintenance. I wish I had bought earlier.
Worth to buy!
This filter does its job very well. I felt more horsepower instantly after replaced the filter even though I didn't have equipement to measure how many I have gained. It gives me more confidence to pass or enter freeway (I'm not encourage car racing, so drive safty is the most important). Another benifit is the engine runs smoother and quieter than before. It seems didn't give me significant improvement on gas saving, but compare with the car performence its means the gas was used more efficient. Besides, the filter is reuseable, you only pay 2-3 times more than the paper filter on the first purchase, but will save money afterward (needs cleaning and refilling work).
Honda replacement air filter
I don't know how well the product performs, but the manufacturer's packaging contained nothing (other than a product number)to identify what vehicle the filter was designed to fit, or exactly how it was to be installed. A general information sheet accompanying the product stated that one of the first things to do is to verify that the product is the correct one for your car. TO do this required leaving the garage, going to the amazon site on my computer and looking up the number on the box by paging through 5 screens of filters before locating the correct one. It seems strange to me that when ordering a replacement part, such as this filter, you have to check every filter shown on the amazon site until you find one that fits your car. Normally, you would first identify your automobile make, model and year and then you would be told what filter fits your car. The Amazon process appears to be backwards and very time consuming. Cleaning instructions for this filter were also sketchy and confused. After all of this, I hope the product performs as advertised...especially since I had to make my best guess as to how it was to be installed.
