Neil J. Chalpkin, Mitcham, England
I've used K&N filters on both motorcycles and car's for 30 years and can say without a doubt they are the best on the market, the quality is second to none and the fact they can be cleaned and used again and again is brilliant. I will continue to use K&N's on my vehicles whatever they maybe because, in my humble opinion. you can't beat them for performance and quality, full stop.

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.
