Intake Manifold

[Vinnie]

Has anyone replaced their intake manifold with any performance intakes? If so which ones did you use….

What year/engine is your truck?

Be careful of looking for performance upgrades in a heavy truck. 10 extra HP at 5000 rpm at a expense of torque down low is not a trade off most of us want.

yes they have but they did FULL exhaust with shorty headers...they didn't see any improvements...don't know exactly which brand...I think Gibson shorty headers...again...they didn't see any improvement in performance...there are a couple that also did this but they did a full rebuild and added a supercharger...goes without saying
