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.
Quick and easy
I recently sold my MK3 Focus ST and upgraded to the MK4 ST looking forward to some new bits once developed.
After purchasing the mountune m330 upgrade all I needed was this to add to the experience!! Again great service from the team, gave me plenty of help installing with great response time. Only thing is I’m sad to say my car has recently been stolen and I’m hoping the team at mountune can help me out when I Come to needing another upgrade!!
Thanks for the great feedback Joseph, but we're obviously upset to hear that your pride and joy has been stolen - if you're planning on getting another one once everything's sorted out, please get in contact and of course we'll help!
