From what I've seen the Delphi 03+ 85mm MAFs have a different part number than the 01-02s. I know the 03+ came without a screen, besides that, are there any other differences? Thanks!

 

anyone know?

 

TTT Maybe my next mod along with a 85mm lid to get a little more air through the 90/90. Anyone know how much benefit this may be with a bolt on mild H/C setup like mine??

 

It's worth 7-10rwhp on a H/C setup.

Anyone know the answer to my original question?

 

difference between these mafs gm# 25341604 and 25168491?

 

I was told an 03 truck MAF was just as good and 40-50 bucks on ebay. True?????????

 

im pretty sure the reason the Camaro and Corvette MAF are different part numbers is because we dont have 85mm MAF. I thought the 2004 Z06's came without the screen not the '03, but im not sure. On a stock or bolt on car it really isnt worth getting a 85mm MAF, for a h/c it should be on your list if your not going to do a SD tune.

 

oh wait did you mean 01-02 Camaro or Corvette? i meant Camaro but i just reread it and i think you meant Corvette

 

I think that there is just the screen difference. I have a new one, in the box, never used, I'd sell for less than I pais for it. I think it is the 03 version.

The calibration may be different from year to year, which really isn't going to matter to anone, because most are going to get a new tune after installing this.

 

There was a GM part # shift on the 85mm screened
MAFs, but do not know why.
