Stoffler Tunes Ford Focus RS

German tuner Stoffler has developed a performance upgrade package for the Ford Focus RS. The kit consists of an upgraded downpipe and exhaust system, upsized intercooler and a remapped ECU. The result is 51 extra horsepower to bring the power up to 356 horsepower from the 2.5 litre turbocharged engine. Torque figure has also increased to 525Nm.

The Stoffler tuned Focus RS also has some exterior tweaks which include side skirts, black wheels with red ring surrounds and a matching paint job to show that this is no normal Focus RS. The Stoffler performance pack costs 2,900 Euros.
