The MP215 upgrade is awesome! Pulls much more urgently and the car feels so much more lively! I was in doubt for a few months before upgrading my ST but I wish I had got it done sooner. Much more pull in 3rd and 4th gear. Perfect performance upgrade for the Fiesta ST!
Easy to install , stupidly good results. Simple and clever kit , love it thank you very much Mountune !
After driving a stock ST for 3 years, the improvements with the 215 kit are very noticable, despite the modest difference in numbers. There's more pull across the range, but the best bit is that the engine feels a lot more free at the top end. I would previously change up around 5k to avoid the performance drop off, but now quite often just let it rev out. There's also a nice improvement in induction noice. Good stuff mountune!
