Fitted K&N filters on many of most of my cars, (including a B 60's reg ford Zodiac in the 80s ) as always, no problems. Car drives with better response and an increase in overall mpg.

Its always good to know that there is a product out there that just doesn't only provide clean air to your engine, but also allows you to get more performance and economy without having to retro-fit any components. Awesome!
