Isn't saying a GM MAF (BTW... there's no apostrophe for more than one
MAF!) sort of like saying a VW MAF considering a Golf I4 and VR6 MAF are
different things so why would one assume that all GMs use the same
MAF?  Perhaps it would be better to get the model and year of the
vehicle that has the correct MAF?

Just a though...
