I ordered this filter on Wednesday morning 22-01-2014 and it arrived at 11.am Thursday 23-01-2014. Fantastic service. Half an hour later it was installed, I then went for a drive through the town and saw an immediate 50 percent improvement> Then drove out of town on 40 mph roads. The performance increased by another 35 percent approx. I am now getting an average 32 mpg around town. My car is a 2005 Ford Focus C-max 1.6 petrol which was giving poor mpg. Your filter is excellent Thank you.

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.
Dean Barton, Lancs, United Kingdom
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.
