HouYeen Hood Air Box Intake Filter Vent Cover Trim Black for F-ord Focus MK3 Kuga Escape MK2 M-azda 3 BK

Only got 5 stars because it was cheap. Fits well with a bit of force, seals well against bonnet. Slightly more intake noise, probably lots more heat soak. Purely a cosmetic part. 2012 ST

Took a punt on this after seeing the 1 other review. Have to say I am really pleasantly surprised. I didn't want the RS badged airbox, and I didn't want to cut my original box, so thought I'd try this. Took a little bit of persuasion but did go on and screwed up tight in the end. Looks great and sounds great too, a little more turbo noise but unintrusive. The seal also fits perfectly against the bonnet preventing hot air ingress. A really good buy. The picture is of it fitted in my 2015 Ford Focus ST (ST250/MK3.5/facelift).

Don’t see any performance difference other then it looks cool on top air filter

Like it fits for aftermarket partDislike had bit fiddling to get it on

Straight forward swap,no issues. Build quality same as the original.

Fitted to my 2017 Focus ST3 perfectly

Good but not all the screw holes line up for an ST but it's secure enough and sounds good when combined with the mounttune filter

Direct replacement for OEM air box cover. Only problem I have is that not all of the bolt holes line up, so I ended up fastening it with 3 instead of 4.
