Is your Ford or Mazda running rough, stalling, or getting poor gas mileage? The mass air flow (MAF) sensor might be dirty or faulty. This is a brand new replacement MAF sensor from universeparts. It comes with the housing already attached (w/ housing). Part number 97M3216G97. Fits a range of vehicles like Ford Aerostar, Escort, Ranger, Taurus, and the Mazda B3000. Cross-references to numbers like F67Z12B579BA, MF21223, and others. UPC is 602168510720. It's a direct fit, so installation is usually just unplugging the old one and plugging this in—maybe a couple of screws. Cleaning the old sensor sometimes works, but if it's truly bad, a new one is the way to go. Comes with a 1-year manufacturer warranty. Get your engine's air/fuel mixture back on track and improve performance. A common fix for many drivability issues.
