Description
A properly sealed upper rocker cover is non-negotiable for keeping oil where it belongs—inside your engine. This JAMES GASKET cork gasket combines proven materials with precision engineering to deliver a leak-free seal that holds up under sustained heat and pressure, whether you’re street driving or on the track.
