I'm interested in someday getting this mod done seeing as how the intake and heads seem to be the RWD 3.4l engines weak point. I have read in a few different places about the intake and aluminum heads from the 2000's pontiac grand am gt and how they are pretty much bolt-ons for the RWD 3.4 and how they flow MUCH better than what comes stock on the RWD 3.4l. But when I get a mod for my car I want the best.....so is there a better fit? When I say better fit I mean better air flow and more power, minimal modification to get it to bolt on.

Please also let me know if there are any other parts/mods I would need to do to make this work.
