The Germans at Stoffler managed to create a performance tuning kit for the Ford Focus RS. The 2.5-liter engine that standard equips the American model develop 305 horsepower and 440 Nm of torque but the tuners from Stoffler managed to increase these figures by recalibrating the ECU unit, mounting a bigger intercooler and improving the downpipe.
Thus, the Stoffler Ford FOcus RS develops 356 horses and a torque amount of 525 Nm. The German tuners offer also a GGR filter (€695), three optional exhaust systems but also new alloy rims. Instead of the most performant exhaust system provided by Stoffler that costs €2300 you can choose the CSC exhaust system (€1290) or the Milltek one (€990).
The tuning kit prepared by the tuners from Blumberg for Focus RS includes also new 200 cell sport catalytic converters but also an MOT certificate issued by the Technical Control Board. The Stoffler Ford Focus RS performance tuning kit costs €2900.
