Re: Quick ?
If you filled the baffles with foam, the only thing I am thinking is that the foam might start peeling off and being stopped by the MAF screen, or being ingested by the engine, which I would assume would be bad. If you were to find a foam that could withstand the high speed air going past it, I would say that would be an excellent idea. The lid's are designed to flow air much better then the stock setup, and I would assume even better then the baffles filled with foam. Plus, nobody I have shown my engine compartment to knows any work has been done at all. Lid, MAF, ported throttle body, and an ls6 intake ... can all be done without making anything look "aftermarkety".
Reaction time needs to improve, and your 60ft should be a tad lower with the nitto's ...
