GVR-4 1g/gvr4 intake manifolds are there any differences between the years?

[4gfun]

I have a few intake manifolds laying around and want to make sure that I have the best one for my GVR-4.. I know that there was a Cyclone IM and some early EVO ones. None of my intakes say Cyclone on them and all have EGR provisions.

Other than that, are there any other differences or are they all exactly the same?

Thanks!

I have tried and tried but I can't find any differences on a 1g. Can anyone confirm that there are no differences?

They're all the same.

The cyclone is technically a 1G manifold with variable runner lengths, but that's not a USDM product; as the Fonz said, assuming you're talking about the USDM, they're all the same.

Cyclone was JDM, those cars were also 16g, but that's a whole nother topic.
All usdm intake manifolds are the same auto vs manual, doesn't matter either.
:Edit, all 4g turbo Intake manifolds.
