US and mainland Europe customers are not the only ones who can buy a factory-fitted Mountune performance kit for their Ford Focus ST hot hatches.

Ford has announced that the performance upgrade from engine tuners Mountune is from now on available in the UK as well. The kit increases the power output of the Focus ST’s 2.0-liter EcoBoost engine from 250PS (247hp) to 275PS (271hp) and does not affect the vehicle warranty – provided that it is fitted by a Ford dealer.

The upgrade kit from Mountune includes a large capacity alloy intercooler, low-loss cast crossover duct with silicone hose, high-flow dual-entry air filter and specially developed performance-map calibration. The package not only produces a 10 percent increase in maximum power output at 5,500rpm, but also an improvement in torque from 345Nm (254lb-ft) to 400Nm (295lb-ft) at 2,750rpm.

Mountune’s MP275 upgrade kit is priced at £1,195 ($1,814) including VAT plus fitting, which takes two hours.

“The 2015 Focus ST 275PS upgrade is the latest addition to a wide range of Ford Performance parts and accessories from Ford dealers. It enables Focus ST owners to experience even more impressive performance, while offering the reassurance that the upgrade will not affect warranties,” said Kevin Griffin, Ford of Britain sales director.
