Just wondering if a stock gm maf off of a 01-04 zo6 have a screen in them or not. Anyone have a part #
Thanks

 

01's had the screen...02's thru 04 did not. Can't help with part numbers.

Part number for the 02 is 25341604, it has no screen. Hammer is correct.

 

Thanks is one better than the other

 

Its always a debatable subject, the way I see it is that if your running a set up that is choked off by the MAF, tune it on SD and remove the restriction, the screen is supposed to direct air flow so it can be read accurately and the car can have better fuel economy and emissions since the proper amount of air is being measured.

But again GM felt that for the z06's it benefited from not having the screen, but again it should be tuned for that to get best results.
