K&N Replacement Air Filter
  • Designed to Increase Power
  • Million Mile Limited Warranty
Casey Sanders, Shakopee, Minnesota
I cannot say I noticed any power gains but that is okay because the filter seems to be very high quality and I can use it for many years to come. My car only has 20,000 miles on it and I expect for it to easily pay for itself.
Bruce Gordon, Canton, Massachusetts
Ordering was easy. Shipment arrived on time. Installation was a breeze, and now acceleration through 1st and 2nd gear is much smoother and more powerful.
Colleen Fixsen, St Paul, Minnesota
The fit was right. No trouble. No leaks. Look forward to cleaning instead of replacing. This is the first time I've used K&N on a car. Have used K&N on my old motorcycles for years. Always liked their performance and reliability.
