Mustang Pro-M Custom Tailored Mass Air Meter
Improve the performance of your 5.0 or 4.6 engine with this 1989-2004 Mustang Pro-M mass air meter! Pro-M custom tailors this mass air meter to your specific application, based on the information you provide! This mass air meter features a large, 92mm diameter that improves airflow over the factory mass air meter. The non-flanged housing is designed to bolt up to either your stock airbox or aftermarket cold air intake. Increasing the diameter of the mass air meter improves the throttle response of your Mustang, as well as provides more air for increased horsepower! A high flow air filter is included to maximize airflow. Pro-M pre-calibrates this MAF to work with your specified fuel injectors so you're ready to install upon arrival!

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.
