Just out of curiosity...
First off, thanks to all ya'll here on Dodge forumn, I've learned alot about my truck and different mod or repairs that can be done. Now I have a question to ask. What the heck is a Plenum? I first heard bout it on a cat related post and I'm just so dern curious bout what it is. Anybody want to fill me in?

Your plenum is a plate bolted under your intake and there is a gasket in between. Dodge had a bad design when they built these trucks. They have an aluminum intake with a steel plate. Look down your throttle body and see if there is oil build up. If there is than your plenum gasket is shot. When you order new gasket get a new aluminum plate. Google search hughes and they have kits.

The empty space inside the intake manifold. There is a plate on the bottom of the intake that seals the plenum, but, it was a rather poor design..... and the gasket there blows out. (the bolts are too long.) There is the stickied plenum thread will that will you a lot more than you ever wanted to know about the plenum.
