Plastic.
Most of the 2500s in our fleet have had them leak.
We used to see that from time to time in 2001, 2002ish. And that was a gasket issue.
Anything 2007 and newer, I have not once had an intake itself cause an issue. And we run a *f-wordton of trucks through this shop.
Possible regional thing. Sometimes talking to guys at the training centers guys in certain areas see different problems for whatever reason.
You want to talk broken exhaust manifold bolts though...Ferd and Dudge have that issue too however.
