Dennis, The design of the opening in the gm cover is to give more protection from any water that might make it through the seams of the hood or when opening the hood when wet. The modified cover,donaldson and halltec do not afford that safty precaution. Will you definatly have a problem? NO. Is your setup as safe? I dont think so.

This has a larger hole than even the new 02 cover, is inexpensive for the extra HP you get, and there are no hydro lock worries. Also easy to change back to stock.
Well crap ! I just ordered one from LAPD.Mark S. said:According to a test conducted by Corvette Fever, you will need to also install the '02 MAF in order to notice any appreciable gain in HP.
Sorry for the confusion. I ordered the '02 box with a K&N and was only saying crap because he said it wouldn't do anything for me.ZO6LS6 said:You DO NOT need an '02 MAF,,,,,,,,,,the one you have is QUITE sufficient for the '01.............
Why dod you order a '02 MAF????:-?
