Vauxhall Ecotec (X20XEV) Q420 – a mechanical profile camshaft, reprofiled
Suitable for: Vauxhall / Opel Ecotec (X20XEV)
The price is for your existing pair of camshafts to be re-profiled to Q420 spec.
These are mechanical profile camshafts, designed to operate at much higher speed than standard engines. These cams consequently require solid cam followers. They also require pistons with deeper valve pockets, to accommodate the higher lift. Race quality valve springs should also be used to cope with the high rate of valve acceleration.
