Dude. MY1997 LS1 Corvettes, some of which built in 1996, had plastic intake manifolds. They're holding up just fine.
Plastic breaks down with age.......and in 10 years, you might start to see some of those 1997 plastic intakes wearing out. GM spends billions of dollars in engine design; especially for the engine going in their halo car. I think they've got a leg up on you.
I know a guy with a 1998 C5 with 140k miles on it. 10 years and 140000 miles, and the stock manifold is still going strong. Do you plan on putting that many miles on your Camaro? If not, then stop worrying about it.
