Default Need help identifying this MAF
Hey guys, trying to finish up the details on the LS swap into my nova and this is the MAF that came with the 2002 z28 camaro. It doesn't look stock to me, can someone help me figure out what it is? Thanks

Well what I know:

* Not stock delco part
* 3.5" OD
* 85mm opening
* No screen
* 3 pin so its for a gen 3
* has no locating tabs on the 3.5" OD
* has hand etched part number on the bottom.

Anyone got any guesses?

Might be an ebay knock off? looks like it's definitely been fiddled with. Is it making the engine run poorly or causing any other problems?

Could be the Granatelli or could be aftermarket MAF
ends on a stock Oreo MAF center section. Either way
it's an unknown quantity, tuning-wise, that you're
better off without at least until you have no other
questionable calibration aspects in the tune*motor.

What would be a good 85mm stock MAF to buy as a backup? What year corvettes and trucks did they come out of?

Turns out it was a 75mm EBay-ish MAF. I replaced it with a Delphi 85mm MAF.
