Mountune, innit
Want your RS to go even faster? Then try the o icial Mountune kit, which includes a new air ilter, alloy crossover pipe, recirculation valve and ECU remap, and has been co-developed by Ford Performance – so probably won’t explode within minutes and doesn’t void the factory warranty. It costs about a grand itted, and boosts the engine to 370bhp and 376lb ft, dropping the 062mph time to 4.5sec in the process.
