LS2 Plastic Intake Manifold

[Keith Tedford]

Are there any water passages in the factory LS2 intake manifold? A guy was telling me about his plastic Buick intake cracking and it allowed antifreeze into the engine while sitting causing hydraulic lock. Not a good situation.

Yikes! When I had my LS1 intake swapped with the LS6 intake, I don't recall any coolant passages. I imagine the LS2 would be similar? I know coolant goes through the throttle body but that's as close as it gets to the intake.

I believe that the 2005 got the heads from the 2004 Z06, so I would imagine that the intake would be the same. Thanks.
