Vehicle Fitment

This product will fit the following Focus years:

Rated 5 out of 5 by from Lid only works perfect I wanted more intake sound from my 2018 Focus ST and had read about this RS replacement box. Just as I had suspected there was no reason to replace the box since it was the same so I just replaced the lid with the new RS one. As I had read the only difference in the four hexhead screws that hold the lid on the RS vs. the old box was that the new box had 7mm hex heads and the old 8mm. The screw threads and length are identical to the old ones and as a matter of fact you can use old onew screws. The K&N filter comes as an addition to an already installed factory paper filter that is in the airbox. Personally, I wanted an open end filter which this K&N is not so I went with a Green 7159 open end filter for even more intake noise. The lid is a little finicky to get on wether it be the old lid or new one since it fits together tightly. Just line up carefully and press it evenly on then when aligned in place tighten screws. I'm happy with the looks installed, the performance, and the price. I think this direct fit is as good as many so called cold air intakes that cost hundreds but for a small purchse cost for this RS it's the better deal.

Rated 5 out of 5 by from Focus RS Air Box Tried to just replace the top part of the box as the lower box was practically the same in the ST. However, low and behold the RS was made England and the screw threads were slightly larger. So, do not try doing this. I do love the sound of the new bow though. I made me smile the first time I turned engine on.

Rated 5 out of 5 by from Great Mod (Once Installed) Perhaps I'm not as mechanically inclined as the other reviewers, but I did not find it to be a "slam dunk" to remove the stock ST air box and replace it with this one. It took me well over an hour to do the swap. Ford must think it's easy as they do not provide any instructions. However, the RS air box looks and sounds great once installed! Highly recommend, just be realistic about your installation chops.

Rated 5 out of 5 by from Fits perfect on the ST I fitted this on my ST and fits perfectly. It looks good too. One thing to notice is that the rubber seal rubs on the sound board under the hood.. no big issue though.

Will this fit a 2015 Focus SE

Asked by: Roofer3347
I have a 2015 Focus SE and I was able to use the top of the Air box and filter with no issues. I have heard you can use the bottom of the Air box as well but I have no issue with the resonater. I have since moved the lid to my ST but I will be buying another to put back in my SE.
