Engine Air Filter Compatible with Ford Focus ST RS 2009-2018 Cold Air Intake,Washable And Reusable,Fit C-Max MKC Escape Grand Kuga Transit Connect Tourneo Air Filter Accessories

Nice filter, fit perfectly on my 2014 Focus St. This really changes the sound of the vehicle. The intake is noticeably louder and you can hear some turbo noise (not blowoff sound) as well which adds to the whole driving experience. Overall I'm very happy with my purchase

Fits my 2017 focus RS like a glove.

Looks amazing and sounds insane very happy I’ve always used the k&N filter but these gives you the best airflow

Great fit, slight increase in throttle response and mpg. Don't bother with the supplied screw driver, the one I got was for some different kind of screw

The air filter fit perfectly, however the t-handle wrench that came with it doesn't fit the head of the hex-head screws on the filter cover. I'll just use it as a bit driver instead.

Went on easy, T handle is useless, but it’s a good filter.

Works great, sounds great, improved performance too.

I doubted this would be any good but I was wrong, the sound and the little extra HP it added was very impressive
