Just a tip: If you have a V8 E34 (probably E31, E32 and E38 as well), don't buy a reman'd MAF from AutoZone (CarDone).

They listed this MAF as fitting my car, but it quite obviously does not It's almost 2" smaller in diameter than my MAF.

Not even close to the same size. So now I have to find a place that will have a MAF for my car. Any suggestions outside of the dealer?
