Rob Goldstein, Santa Clarita, California
Great product, I immediately noticed a difference over the paper filter that was in the car before. A little intake noise and smoother acceleration feel from idle to about 3000 rpm. It doesn't have that gargley sound. A good investment for the IS300 overall.

Having used K&N filters before, I invested in a replacement air filter element for the quality, performance and durability I trusted I would get. I wasn't disappointed and was delighted that I could order this directly even though my car is an unusual Japanese import and surprisingly the price was better than from specialist tuning companies. The car noticeably pulls better since the filter was replaced and coupled with other recent tuning changes has made driving much more enjoyable. If I'd known I could have ordered directly from K&N I may have done it sooner. Very happy customer.

Have had two K&N filters for two different cars and really pleased with the result.
