If you drive a 2015 Ford Focus ST but are already jealous of the 345-horsepower 2016 Focus RS that's on the horizon, Ford Performance has a new upgrade kit that could be a great compromise. Developed by the Blue Oval experts at Mountune, the MP275 setup takes the hot hatch's output to 275 hp and 296 pound-feet of torque when running on 93-octane fuel. Those are gains of 23 hp and 26 lb-ft, respectively.

Providing much of the kit's extra oomph is a recalibrated ECU with more aggressive engine mapping. The company claims that the upgrade also improves throttle response, and it keeps the Focus ST 50-state emissions legal. In addition, customers get a Mountune high-flow intercooler, a new air intake, and all of the necessary hardware to mount the components in the engine bay. For those concerned about reliability, when an authorized Ford Performance technician installs the parts, the Focus maintains the factory warranty. The MP275 kit currently retails for $1,900 on the Ford Performance website. For added protection during harsh weather, customers can also get an end cap for the cone air filter for $15.

Ford Performance Upgrade Kit for 2015 Focus ST Boosts Output to 275 Horsepower, 296 Lb.-Ft. Torque

• Ford Performance mountune Focus ST kit for 2015 optimizes performance without sacrificing reliability

• Sold through Ford Performance Parts, the kit maintains the base car's factory-backed three-year/36,000-mile warranty

• Package adds 23 horsepower and 26 lb.-ft. of torque

DEARBORN, Mich., Aug. 18, 2015 – Focus ST customers can get more performance out of their vehicle thanks to a new kit from Ford.

And on that front, the new Focus ST mountune upgrade kit delivers in spades.

The idea of a street-legal, reliable, largely stock 2.0-liter four-cylinder engine making nearly 300 lb.-ft. of torque might have seemed ludicrous 10 years ago, but the components of the MP275 Focus ST performance upgrade not only combine to produce up to 296 lb.-ft. of torque with 93-octane fuel, they are designed for maximum reliability as well.

"The 2015 Focus ST MP275 upgrade is the latest addition to Ford Performance's vast Focus and Fiesta performance catalog that gives enthusiasts the components they need to take their car to the next level," said Adam Gair, product manager, Ford Performance.

When the parts installation and tuning is performed by an authorized Ford Performance technician, Focus ST retains its factory warranty – a huge benefit for any customer looking to get the most out of the ownership experience.

The heart of the system is a performance ECU calibrated to deliver a more aggressive engine mapping program, including a quicker throttle response, without compromising durability. Power spikes from 252 horsepower to 275 horsepower.

Unlike many aftermarket kits that compromise reliability and driveability on the street while also hampering emissions, the mountune system keeps Focus ST street-legal in all 50 states.

The upgrade kit includes:

• mountune induction kit
• mountune high-flow intercooler
• mountune mTune handset
• All installation hardware

A mountune air filter end cap can be added to the mountune high-flow air filter to control sound and provide air filter protection in harsh weather conditions. More details on the kit can be found at the Ford Performance website.
