Pro-M Mass Air Meter
Upgrade your stock mass air meter on your Fox with a 1989-1993 Mustang Pro-M mass air meter! This Pro-M mass air meter features a massive 75mm tube that allows you to really open up your engines air intake! When installing a larger mass air meter on your car you are allowing more air to enter your engine. This helps produce more horsepower and an increase in throttle response by the sensor relaying a message to your computer that more air is coming in. This allows more fuel to be added to maintain the proper air to fuel ratio. This Pro-M mass air meter come with factory connections allowing for a quick and easy installation!
This part number is designed to only work with 19lb fuel injectors and a stock Mustang air box!
This Pro-M mass air flow meter does not come with a CARB OE number for California residents.
After doing a lot of research I decided to order this MAF, to go along with my new trick flow top end kit, after everything was bolted up and ready to go I kept getting a check engine light with code 66, well long story short and two sets of spark plugs and about 8 hrs of labor later the sensors bad. Pro m racing wants to send it back and check it out before they will fix it or have me pay to repair it and the car being down weeks before I get another, so I just ordered a different brand and all is good. Nothing towards LMR at all!

I bought this mass air flow about couple weeks ago and I'm so happy I did. The stock. Maf just could not keep up with my hci combo! Fitment was perfect and it gave me much better drivability and performance!
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.
