This oil catch can kit helps prevent oil vapour from entering your intake manifold, keeping your intake air cleaner and reducing the risk of carbon buildup from burned oil.
Does it work? YES. See the pic with the measuring cup full of oil? Had it not been for the catch can, that oil would have gone into the intake manifold!
Fits all V8 Vantages, including 4.3L, 4.7L, and V8VS. Does NOT fit V12 cars.
