The Radium Engineering Baffled GM Oil Cap is an anodised billet aluminium oil cap for General Motors LS and LT engines, and suits both oil cap styles used across LS engines. Out of the box the top port is fitted with a 10AN ORB plug, making it a simple direct replacement for the OEM cap with nothing else required.
Remove the centre plug and underneath is a cleanable, reusable stainless steel baffle for air/oil separation. The 7/8in-14 threaded top port accepts 10AN ORB adapter fittings, so the cap can form part of a custom crankcase ventilation setup.
