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.

If you are always going to keep your car get the intake and filter kit, if not buy just the filter. You will save money on gas, never have to buy a new filter and have more power all around, perfect product. This is something you should buy immediately for any vehicle you own.
Albert Eilers, Cincinnati, Ohio
I was considering adding a cold air intake, but read that I could achieve the same results with a replaceable K&N air filter. I choose the air filter and have been delighted with the results. I have improved air flow and a more responsive engine. Very easy to do and less cost. What's not to like?
