Vauxhall C20LET C20XE BIG Runner Inlet Manifold Vapour honed 90448197

BIG Runner GM Inlet Manifold for C20LET & C20XE engines

Vapour honed & treated with ACF-50 for a longer lasting factory finish.

Complete big runner inlet manifold that is the best factory inlet for flow on forced induction C20XE & C20LET engines, so great when wanting to produce up to and sometimes beond 400-420BHP on a factory manifold. We have seen over 400BHP achived on these manifolds consitantly.
