The mountune high-flow cotton gauze panel filter for the Mk4 Focus ST provides an instant improvement in both performance and induction noise and is easily installed in less than a minute.
Each mountune filter is manufactured using a multi-stage process resulting in a great fit and virtually no seepage of frame material into the filtration media producing the maximum available filter area.
Note: Also compatible with Mk4 Focus ST-Line 1.5 turbo models.
Speedy delivery and fitted within minutes.
After ordering, received the parts in The Netherlands within 3 working days. Very happy with the service from Mountune in these difficult (Covid) times! After receiving it took me about 5 minutes to install and replace the Original airfilter. Not yet driven the car, but looking to the other customers stories, it will be a noticeable difference. Hopefully Mountune will also come with the intake hose for the 1.5 EcoBoost. And if so, I'll be again a happy customer!
