  • GM 85mm 5 Pin Meter

    GM 85mm 5 Pin Meter

    Pro-M Racing, LLC. mass air meters for GM applications appear to be exactly the same product that you have seen advertised by other manufactures. All aftermarket manufactures (Pro-M Racing, LLC. included) start with the same production GM meter. The entire housing is machined, allowing it to flow more air than the stock meter. This is where the similarities end. Modifying the meter housing allows the meter to flow more air, but in the process, the calibration of the meter is thrown way off.
