Worth every penny

I was considering getting the upgrade for some time but after hours of research and reading reviews from fellow owners both on here and the OC forums, I must say it was one of the best purchases I've ever made! The staff at Mountune HQ were very welcoming and friendly and make sure you are comfortable throughout your stay. The upgrade gives the car so much more grunt and sucks in air like a whale, keeping the engine nice and cool. The only problem now is I want to spend much more on Mountune upgrades that I can't afford. Thank you !



I knew when I started to look at the Focus ST that I would give it to Mountune and I have not been disappointed with anything they have done. Having only driven the car for a little while before getting this installed it's hard for me to talk about the differences in detail. I did notice much more instant power and I like the sound (it's a rumble/gurgle) from the air intake. I had this fitted along with the roll restrictor (which is a must as it stopped the horrible wheel hopping when accelerating hard) and the short shift arm. I have since had the Quaife slip diff installed, which is amazing and I would want to drive the car without it now. Although I only originally planned on getting the MP275 I'm booked in now for the MR300 and Clubsport suspension and I might ask if they can fit the re-circulating valve as everything I get Mountune to fit makes the car better. And I mean all round better, not just faster.

Finally ready to post my review after a couple of months of driving. As many other customers have said this package really awakens the ST250 which always felt quite restrained to me and a little underwhelming if honest. The extra power takes the car to where it should be, providing a shove back in the seats when accelerating hard. 3rd gear feels much more eager and fourth is a beast. Love the added noise of the induction kit too. Just had a Dyno produce 285 BHP so really pleased with the gains over stock. All in all would highly recommend.
