About This Brand

Pro-M Racing

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 vehicles. PRO-M manufactures 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 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 2% of the OEM's perfect baseline. (In comparison, OEM meters are typically held to within 6 percent). Quite simply, despite their claims, no other company even knows what this baseline is. For those who choose to have their vehicle professionally tuned, all of our meters are supplied with a flow data sheet. The flow data sheet provides extremely accurate and invaluable information for tuners, greatly reducing the time needed to properly tune your vehicle. All of our mass air meters can be installed in a matter of minutes and will provide immediate results.
