Plus, you can send all of your K&N filtered air directly to your engine with our wide selection of K&N Cold Air Intakes.

K&N Air Filters Reviews
Check out this recent K&N Air Filters customer review: Phillip I from Crawfordsville, IN says "I received my K&N drop-in filters a little 0ver a week ago. I have driven two out of our three vehicles fairly reasonable distances during that period of time. I have had my Scion XB and Nissan Pulsar on the road both in town and on short road trips. The XB is performing fantastic. The initial torque off of the line is not to be believed. Passing power is also greatly improved. I haven't driven enough to go through many tankfuls of gas, but I feel confident that my mileage has improved at least 2 MPG.The Pulsar seems to be even more frugal at the pump. It is our "fun" car and is even more so with the addition of the filter.To sum up; I could not be happier with my purchase. It has been a great value for the money.yours truly,Phil Ingersoll"
