Lmk gang, i got a KAT

MAF's can be elusive , defective , good , and a 'question-mark" . When I had the typical performance problem, I acquired one from the bone yard , to substitute , ya know. And it turned out NOT to be a MAF problem . When the car ran normally again , hey , NOW I HAVE TWO MAFs .Both good , So the moral here is , because I've substituted them many ,many times again in trying to diagnose problems that turn up now and then - when your car is running well , and you love your car , and you want to keep that car , acquire a ' SECOND alternate " MAF .
To have on hand for a quick SWAP , and take the MYSTERY out of , " hmm , Dah I have a bad MAF ??" .

One of my cars I swap the MAF every A/Filt chng.I blast MAF cleaner & store it for next swap - works well

To your question : Because there is Fake News , probly Fake MAF too , yours I can't tell ,someone here can tell ?

Yes, that's a Chinese repop of a Z32 MAF. Doesn't necessarily mean it won't work, but I sure wouldn't trust one.

thx guys
