Incredible performance without sacrificing reliability!

The Focus ST is a remarkable car and with the addition of the mountune MP275 Performance Upgrade, it’s even more amazing. With optimized power and performance, the MP275 Upgrade adds a level of sharpness that enhances the total driving experience. The MP275 Upgrade has been engineered to extend the power band of the engine resulting in an increase in horsepower and torque across the entire RPM range. The added power provides an even more enjoyable car that is perfect for spirited driving and carving canyons.

An essential element of the MP275 Upgrade is the mountune Upgraded Intercooler. Our intercooler is more than double the size of the original intercooler and provides cool, dense charge air to the engine all the way to redline. Additionally, the air intake system has been improved to allow greater flow to the turbocharger for added power. Backing up the mountune Intercooler and air intake is our performance ECU calibration (tune) engineered to add maximum reliable performance and drivability.

Developed in house by our team of experienced engineers, the MP275 ECU calibration has been validated through a wide range of performance tests and durability cycles including the notorious Nurburgring in Germany. This level of testing ensures safe, reliable performance that does not disappoint.

The MP275 Performance Upgrade is a complete performance upgrade system that is endorsed by Ford and legal in all 50 states.

Installation is easy and requires just a few hours. Additionally, your factory ECU is easily recalibrated using the included mountune mTune handset. The mTune simply plugs into your car's OBD II port and quickly transfers the upgraded performance engine calibration in about 5 minutes.

The MP275 Performance Upgrade does not void your factory warranty when installed at any Ford dealer or Mountune USA.

4 of 5 Thumbs up January 1, 2018
Reviewer: John Mez from GA United States  
Just had Ford put in the MP275 so I didn't void my warranty and I have to say the upgrade from stock to this is amazing. It's a little expensive and I normally like to put in the parts myself but this is the first new car I bought so I'm trying to stay under warranty. The torque in the first few years are just enormously noticeable. Parts came in about a week so pretty quickly and no problems. Deff worth the buy!

5 of 5 MP275 December 19, 2016
Reviewer: philip azcueta from sunnyvale , CA United States  
Quality of parts look great. Hardware included are nice and dont feel liked lower grade hardware. One thing i saw on the intake cross over was maybe there could be some more.clean up or finish work done after the cast was formed. My order came in 3 shipments due to backorder but still came in fairly quickly. With the different shippments i think it caused confusion because i was not shipped the adaptor to install the intake crossover. (Yup only fund out during install) i called mountune up and they sent one out the next day. Thanks.

5 of 5 How the FoST should be July 9, 2016
Reviewer: Michael B from Chandler, AZ United States  
The difference is night and day. Torque is available across the range and mid range pulls noticeably harder. This is how Ford should deliver these from the factory.
