Be the first to review part 56-9017
After reading other reviews I decided this was the intake for my 2013 Ford Focus with the 2.0L Duratec engine. Great sound and noticable performance, plus better fuel economy. The numbers don't lie. The provided dyno info was almost exact when I had put mine on the dyno. Nearly 10hp gain through the meat of the power curve.

Installed this product on my 1991 Ford F-150 and what a difference it has made. Definitely gave it more power and about 3-5 mpg better. This was a want for this truck, now a NEED for my other vehicles.

I installed this intake on a 2015 Ford Focus Sedan SFE 1.0L EcoBoost. What a difference The kit is just a filter and a new intake box lid, so you won't get the loud CAI sound....but the throttle response is AMAZING MUCH more fun to drive, much smoother acceleration. Less bogging when the rpms dip too low. Couldn't be happier
