Sorry for asking, I have looked under past posts and for some reason I can find an answer. The Stack MAF is is 65 mm right? The reason I ask is I am buying an adapter plate and need to know what size. Thanks
From my understanding, the stock MAF adaptor is 70/75mm
Try http://www.duratecperformance.com/ and search for a MAF adaptor. It's easy, select the year, make, and model. That's it. A list of upgrades will come up, including the MAF adaptor.
