Pro-M 39lb Injector Mass Air Meter
Ensure your Mustang is calibrated for bigger injectors properly with this 1989-1993 Mustang Pro-M mass air meter for 39lb injectors! Any time you upgrade the fuel injectors you need to change the calibration to ensure you computer matches the increased fuel input. The modern sampling element is pre-calibrated and plugs into your stock harness for a truly plug and play installation. Along with increased fuel support, this 75mm MAF will improve throttle response and increase power due to the larger diameter opening.
Pro-M's Bullet MAF is constructed using a high quality polymer housing that is built to last. The factory housing was a tiny 55mm diameter. This MAF is increased to 75mm in diameter which helps increase airflow and throttle response. The Bullet features a modern sampling element that uses a calibration process that results in a tolerance three times tighter than the OEM calibration. This unflanged meter is designed to fit the factory air box or air filters that mount directly to the MAF with a coupler.
Pro-M Racing was founded in 1989 by Bob Atwood, a Ford engineer who was instrumental in pioneering mass air technology. Pro-M quickly became the most respected name in the industry, offering the only real practical solution to the restrictive production mass air meters found in most of today's production Mustangs. We manufacture mass air meters in various sizes, shapes, and styles, as both direct bolt-in replacements, and in universal designs, to maximize your engine's horsepower potential, by allowing your engine to breathe to its fullest potential. Each mass air meter is individually calibrated specifically for you Mustang or Lighting application on one of our in-house flow benches specific to your particular application, and fuel injector size, eliminating the need for time consuming and expensive dyno tuning. Others make claims, but only Pro-M Racing possesses both the intellectual and physical properties necessary to calibrate your mass air meter to within two percent of what the OEM considers the perfect baseline.
