1 Stars   Didn't work as intended.
By on 1/11/2016
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 air meter a little over a year ago along with about 1500$ worth of other products that were great from lmr I recently put this meter on my car after I pulled it out of my garage the meter worked for 3 trips to work 6 miles and it worked great big difference up top but it failed on me on the freeway now I'm scared to lose another 210$ on another one the meter smells burnt in side and no i did not try cleaning it and yes its in a factory air box with filter I have a c&l on my 1995 cobra and it works great

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.
