Cummins 12V Individual Runner Billet Intake Manifold (WCF100228-RAW)

Billet individual-runner sheet metal intake for the 12-valve 5.9L Cummins, built for drag racing and pulling engines. A large fabricated aluminum plenum feeds eight 2.25" round tube runners, giving far more airflow than the cast intake shelf and a more even split between cylinders at high RPM.

This is a race part that requires machining: the cast intake shelf is milled off the cylinder head and mounting holes are drilled and tapped, and you will need custom injection lines and intercooler piping. The 6" diameter plenum has a 4" V-band inlet with a matching steel flange and clamp for fabricating the intercooler pipe. Head flange ports are tapered to 2" and can be hand-ported larger to match a ported head. Supplied raw.
