Late Model Restoration is your one-stop-shop for all of your Mustang mass air meters! The mass air meter, or MAF, is an important part of the engine. It measures the volume of air that is coming through the intake to determine how much fuel to inject. Upgrading your Mustang MAF can improve throttle response and horsepower by opening up the diameter of the meter. If you are upgrading your fuel system, it is a must to match the calibration of your fuel injectors to the Mustang mass air meter. Otherwise, your engine will not run properly. These meters are calibrated for specific fuel injectors such as 19lb, 24lb, 30lb, 36lb, 38lb, and 42lb. Want to convert your 86-88 Mustang speed density setup to a mass air meter system?
