About This Brand

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.
