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.

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 on one of our in-house flow benches specific to your particular application, either eliminating the need for dyno tuning, or greatly reducing the time required to do so.

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. (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.

Pro-M also manufactures virtually every private label mass air flow sensor on the market. Such highly respected companies as SCT, BBK, Sniper, and others rely upon Prom-M Racing to calibrate their mass air sensors. Even Ford Motor Company relies on Pro-M Racing for innovative products to suit their development needs. We are the source and we set the standard! No one else even comes close, despite their claims. Many have tried, (and are still trying!) but no other company comes close to duplicating our quality, or our accuracy, because no other company possesses the product knowledge, and/or the equipment necessary to do so. No other company has access to our intellectual resources, or to our processes. No other company possesses the knowledge we have to support you in your quest for power, performance, and drivability. Our company, and our products, have always been, and always will be, the standard by which all others are judged.
