Review on BOXI Roadmaster Oldsmobile 8251803030 8250083090 by David Forleo

My Pontiac MAF has an outer bore diameter of approximately 3.25 inches. The outer bore diameter of this mass air flow sensor is 3.5 inches. In the end I manually stretched all the rubber parts of the air intake to make everything fit. Then I realized that this part would not fit in a hard plastic air cleaner housing with a rubber boss. I gave it back to Revane. The return process was very easy. The seller of this MAF sensor should do their due diligence and confirm which GM models this part actually fits. AC then ordered Delco MAF.
