I just bought a MAF from the classifieds and was sent the wrong one and the seller isn't responding. However he did send me an RS4 maf. At this point I think I may just sell it again but I'd like to test it to make sure it's in working order. Does anyone know a way it can be tested? I don't have an RS4 to drop it in to test it...

 

bump, I tried the IM and txt again for a refund. I'd really like to verify it's a good MAF so I can sell it
