K&N 33-2337 Air Filter Product Reviews

This is my thirteenth K&N. Every car has benefited with the improved breathing and they pay for themselves with the increased mpg and not having to be replaced at service intervals. Excellent product and excellent service.

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.

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.
