Saw an immediate improvement in performance and mpg. I have a 2.0 petrol Focus and get around 4-5mpg extra with my K&N filter over my stock one.

Excellent product. Does what it says on the tin. I get around 2-3 mpg extra in my 2.0 petrol focus c max and noticeably faster acceleration. More than happy with my purchase and more than happy to recommend this to anyone.
