K&N Replacement Air Filter
  • Designed to Increase Power
  • Million Mile Limited Warranty
Ted Allen, Redlands, California
Site is very easy to navigate and steps to order flow quickly and simply. This is the third K&N filter I have ordered and like the rest it arrived before I expected and was in perfect new shape. I installed this one on the 2007 Honda S2000 and have not taken any measurements yet, but it does seem to have improved low rpm performance. The other 2 on are my '71 Fiat 124 Spider (Dual Webers) and 2012 Infinity M37. I generally keep our main car for 5 to 7 years, and sport cars for 10 to 15 (except Fiat which I have had since 1977). So lifetime filters are the only way for me to go even if there was no performance improvement.

Excellent addition to the car, easy installation.

The filter received was damaged, but outstanding service to send me a replacement within 4 days. The replacement filter was a perfect fit for my S2000.
