Before I would purchase a car intake for your truck I would PM Tony Mamo @ AFR to get the lowdown. He is R&D Manager for AFR and a FAST intake guru with countless hours porting intakes with the use of a flowbench.

Best of luck with your combo

I don't think the factory manifold is nearly as good as the FAST truck manifold.
