The Powerkit is a genuine factory-fitted Porsche tuning package offered only on the Carrera S that lifts power from 350bhp to 376bhp. You can order it on any two- or four-wheel drive Carrera S with the coupé, targa or cabrio bodies.
In fact it’s a pretty comprehensive affair and includes modified cylinder heads and exhaust manifolds, a carbon fibre air cleaner housing, aluminium intake and, yes, a sports exhaust system and revised ECU.
As well as that 26bhp power hike there’s a gain in torque too, from 295lb ft to 306lb ft although the torque peak now moves up 900rpm to 5500rpm.
