  • Designed to Increase Power
  • Million Mile Limited Warranty
George Baker, Chicago, Illinois
Had a K&N air filter in my Audi and it added a touch of response to throttle, and low and behold, it accomplished the same with my Lexus IS 250. You can actually sense the engine breathing a little easier on take off. I am not talking drag racing here, but rather a more pleasant feel to the first fraction of an inch of gas pedal depression. I did notice that the price has creeped up, say 30 over 10 years, but what are you gonna do. For me, it's worthwhile. How many performance enhancements are there that a novice can install w/o voiding the warranty. A nobrainer.
