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.

"AutoAnything's response to my K&N air filter order was very expedient and professional. The K&N air filter has appeared to add the advertised horsepower to my Toyota Tacoma pickup, but at least with the first tank of gas has not increased the gas mileage at all. The extra performance in the vehicle is a benefit, however I was really hoping to improve the fuel economy. Possibly after several tanks have gone through, things may improve but I must admit to being slightly disappointed to not have gained 1-2 mpg."

"I've been using K&N filters on my past 4 vehicles. You can definitely feel a slight boost in performance. I recently purchased from autoanything and received them in about 4 days after ordering. I installed them in my new vehicle (G35x) which requires two filters (1 minute each). Let me tell you there's a noticeable increase in performance (acceleration mainly). Should also boost gas mileage slightly as well."

"I have driven only 500 miles with this filter. So far I have noticed no significant increase in mileage or performance. The filter was smaller than the regular Lexus filter so it did not fit snugly in the air filter box. The springs on the Lexus air filter cover did not fit on the K&N filter and had to be altered to secure the filter against the housing of the ductwork. I had to bring the car to the Lexus dealer to have them secure the filter cover onto the K&N filter."
