RPD PORTED INTAKE MANIFOLD
RPD PORTED INTAKE MANIFOLD
This ported intake manifold is cut open, then the runners are machined down and the floors and roof of are machined smoothed. The egr ports are remained intact. These intake manifolds will increase spool up and lower egts by ~150 degrees.
Stage 2 intakes keep the egr portion of the intake so you can still have a EGR cooler.
Stage 3 intakes completely removes the EGR portion of the intake so there is no worries about a EGR delete leaking.
ORB bungs are welded in and manifolds are pressure tested.
