Pro-M 47lb Injector Mass Air Meter
Complete your 47lb fuel injector upgrade with this 2003-2004 Mustang GT Pro-M mass air meter! 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 simple plug-and-play installation. Along with increased fuel support, this 85mm MAF will improve throttle response over your factory mass air meter.
Pro-M's Bullet MAF is constructed using a high quality Aluminum housing that is built to last. This MAF size is 85mm in diameter which is a direct replacement for this year model Mustang. 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 meter is designed to fit Mustang equipped with an aftermarket cold air intake.
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.
