I don't mind the plastic intake manifolds at all; they certainly weigh less than cast aluminum, so why the hell not use composite instead of metal. I just don't like covering everything up with a useless, "ornamental" piece of plastic...like the stupid-*** plastic valve cover decorations sitting over the real valve covers on the LS engines!

 

I dunno, composite is lighter but it's not going to have such good characteristics under boost, and let alone if you should decide you want to port match and shiz. having no option BUT to move to after market intake plenum is pretty :ghey:

 

I love the NA-NB valve cover, looks like an old school DOHC italian engine, like fiat or something. plastic is gross, looks about as lust worthy as a computer.

 

Tell that to VW AG. Seems to be working fine for them.

I agree that plastic may not be as aesthetically pleasing as metal in this regard, if we're talking weight savings, I'll take the plastic. Besides, every time I look at the LS series motors, I get all giddy thinking how well they got that damn to flow, while saving weight, all nestled in between the heads.

 

the composites also don't retain anywhere near the same amount of heat like cast manifolds do.
