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.
