-
Billet aluminum MAF bung for 2001-2007 LB7, LLY & LBZ Duramax. The bottom side has a 4.5″ radius machined to fit any 4″ or 5″ tube and includes 2 stainless socket head mounting screws for the MAF sensor.
Billet aluminum CNC machined connector for the cold side of an LBZ or LMM intercooler. This allows you to remove the factory plastic intercooler tube and connect a 3″ tube to your cold side connection! Includes O-ring seal and OEM GM retaining clip.
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!
