Got a 99 Z28 that is mostly stock. I have a Granelli Motorsports M. A.F. sensor. I've herd their garbage. Any truth to that? Will it cause a check engine light? Or should o go with something like an 85 mm AC Delco replacement? Any help would be appreciated. Thanks

 

Thanks for all the responses.

 

i would just go with a stock Delphi 85 Maf. Usually all the Maf's that say Plug and play no tune required have a resistor in them to fool the computer(SLP, Granatelli) etc...
