Description

For more than 30 years, K&N Filters have been the choice in engine filtration. The K&N filter delivers virtually unrestricted flow letting your engine run stronger, cleaner and with greater fuel efficiency.

The secret of the K&N filter is its filter medium. Four to six sheets of pleated and oiled cotton-gauze are layered between two sheets of aluminum wire mesh. This proven design stops dirt, dust and other harmful particles like no other filter, all while clean, power-enhancing air flows freely to your engine.

Just give it a simple cleaning every 50,000 miles and your K&N filter will last for the life of your vehicle. With no costly changes and services, your K&N filter will save you money. And, you'll be helping the environment by reducing the number of disposable air filters that end up in landfills.

Get increased power and acceleration, better fuel economy from a filter that lasts for 1,000,000 miles-get a K&N.

"This is the second car I've had a K&N air filter on. When I installed it on my Subaru Outback, there was an obvious increase in performance, and not a very obvious decrease in gas mileage. The reverse is true on the Maxima. I'm sure performance has increased, but the car already has so much torque that it's hard to tell. Gas mileage has decreased by 1-2 MPG under normal driving conditions. The bottom line is, get this product for power, not for fuel economy."

"I've used the filter in the past with my prior vehicle (Charger SRT8) and felt it was a good product. I recently puchased another vehicle (350Z NISMO) which I purchased the filters for. It seems to have the same good quality I've experienced with the product in the past. Also the ease of ordering through AutoAnything was quick,easy, and the service was above average. Thanks, Pete Plant City, Florida"

"This was not my first time making a purchase of a K/N filter.And will not be my last. I have been a believer in these filters for many years. As a person who loves his TOYS as my wife will tell you.I always install K/N filters in them all!! From the ATVs,motos,hot rods and both of are everyday drivers. Not only is the performance a solid plus,but its enviormentaly friendly. your not always running out to buy a new air filter that is going to just sit in a land fill and piss off mother nature. Livin' GREEN and awsome performance with K/N Air Filters."

"I received a marked improvement in the responsiveness of my BMW immediately after installing the K&N. Leaving stop lights the car's rear wheels broke loose several times. It was necessary to adjust the way I accelerated the car to avoid this from happening. The car had never done that before. Highway 0-60 has improved also. It has given new life to an old car. Wish I'd put the K&N filter in years ago."

"Although an airfilter may not add tons of horsepower to your ride, it is always nice to get some improvment. There was a notisable differance in the power of my truck after installing the K and N. It was easy to install, and the quality is excelent. Probably the best drop in filter you can buy."
