M375 Power Upgrade Kit [Mk3 Focus RS]

The mountune M375 power upgrade allows Focus RS owners in markets not currently supported by Ford to still experience the same factory-backed upgrade experience, via an mTune handset.

Utilising the induction kit and turbo re-circ valve from our endorsed FPM375 upgrade the M375 also includes an mTune handset for easy DIY installation.

Once upgraded, power is boosted to 375PS from 350PS, whilst torque is increased from 470Nm to 510Nm (on overboost), which is enough to achieve 0-62mph in just 4.5secs!

The M375 performance kit includes a mountune high-flow induction kit, uprated re-circulating valve, mTune handset with mountune 375 calibration and two mountune badges.

      M375 UPGRADE

      Finally had 375 upgrade fitted and am more than happy with it. Forget brake horse power figures, it was the increase in torque that appealed to me and yes you do notice it. The fact that Ford endorsed this performance kit also appeals as i don't feel i am loosing any reliability. Car feels punchier throughout the rev range and thats enough for me, car in standard trim is by no means slow but this kit makes a great car better.More than enough performance for road use. I was a bit concerned about increase in induction noise so initially left under bonnet sound insulation in place. However, looking at clearance between insulation and larger crossover pipe I decided to remove it as advised by Mountune and found no problem. Yes I can hear some induction hiss under acceleration but this is by no means intrusive and adds to the appeal of this kit. John.

      A must have!

      The RS feels much lighter and responsive with this pack. A small number increase on the paper but really a big feeling improvement. The car really has at least 350hp now. This pack should be integrated to the stock version. Shame that it is not homologated in every country...
