Add a little attitude to your Cummins billet valve cover! These fill caps are designed to work with our billet Cummins valve covers, HOWEVER, THEY WILL ALSO WORK ON A FACTORY 03+ COVER !! We have taken actual 44 Mag casings and pressed them into a billet CNC machined fill cap!
Our Tappet Cover w/ Oil Separator features an oil catch can with an internal baffle system that helps keep the oil inside the crankcase where it belongs! If your looking for a Tappet Cover, this will be the perfect setup for you!
