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!
Machined steel 4.62″ flange (S400 flat V) for your S400 turbo. Most Borg Warner S400 T4 turbine housings utilize this style exhaust outlet flange. It has a machined recess to accept a 4″ pipe. Includes heavy-duty quick-release v-band clamp. The flange can be purchased separately without clamp NOTE: Clamp included is a VERY heavy-duty clamp. It is not just your standard cheap clamp that breaks the first time you try to take it off!
Our Billet Aluminum Bottom Sump with Integrated Fuel Return System completely eliminates the need to run the return of your aftermarket fuel pump to the top of the tank or cut into the fuel filler neck, therefore cutting install time tremendously!
