    Calibrated for Optimum Performance. Mustang owners are always on a quest for more power. Whether you're starting out simple with a cold air intake or going big with forced induction there is one thing that is holding you back from big power numbers, the factory MAF Sensor. Mass Air Flow (MAF) Sensors are designed to read the volume of air flowing through your Mustangs intake tube. But, unlike the limited factory calibrated mass air meter that "pegs" due to increased air flow, Granatelli's Sensor has been custom scaled and calibrated to accurately read the higher volume of air created by aftermarket cold air kits and force inducted applications to ensure optimum performance.

    Power and Performance. With a noticable increase in airflow over the stock sensor you can expect to see chassis dyno proven increases of 10 to 18 horse power with improvements in performance starting from 2000 rpm's all the way to red line. By installing a GMS High Performance Calibrated MAF Sensor you will not only see an improvement in power and performance, but you will also see an improvement in your fuel mileage and throttle response.

    Plug-N-Play Installation. Designed to be a direct fit plug-n-play replacement for the factory sensor this Granatelli Motor Sports Slot-Style MAF Meter installs with just basic hand tools. No extra modifications are required for an easy 15 minute installation. All necessary parts and instructions are included.

    Application. This Granatelli Motorsports Slot-Style MAF Sensor Meter is specifically designed to fit 2015 to 2017 GT Mustang models equipped with the Coyote 5.0L 4 valve V8 engine. Sold individually.

    I have the BBK 85mm Throttle Body installed with no custom tune, would there be any gain to installing this MAF Meter?

    • The GMS High Performance Slot-Style MAF Meter / Sensor will give you some small additional gains yes. However, you will want to have your car tuned when you do this.

    Is this MAF sensor redundant if you're getting a custom tune? In other words, is the sensor itself a higher performance instrument (more accurate, faster response, etc.) or does this just represent a stock MAF sensor with adjusted parameters? I've read that the "calibration" referenced is similar to a short-cut tune that adjusts airflow parameters of the meter, and won't reset if the car is flashed. I'm not sure if the same results could be achieved through a custom tune, or if the car would actually benefit from both. Any info is appreciated, thanks.

    • I suggest just getting a custom tune. That will accommodate all the mods you have done to give you the maximum performance possible. You do not need a calibrated MAF.

      Great performance addition for my Mustang GT!

      Since adding Borla ATAK exhaust and Holley Intech CAI the performance MAF Sensor was the perfect addition to complement everything. I have noticed improved response and power throughout the entire rpm range, not just the upper rpm range as advertised. It appears that I am also getting better gas mileage than before. I was apprehensive at first because of the cost but I am glad I made the purchase now.

      GMS High Performance Slot-Style MAF Meter

      Very easy install too less than five minutes. Noticeable power gains from zero to redline. I think it enhances my 93 octane tune.

      good part

      I put Flowmaster x pipe resonator delete and axle back Flowmaster Rampage. Knowing all well and good the engine is about how much air can come in and how much air could come out so the fuel would have been done I wanted to do something with Air and fuel I went with a KandN Filter drop in and this mass air flow sensor. I also put in a spiral throttle body spacer. all these things made a great difference when combined.

      GMS High Performance MAF Sensor

      Was looking for a MAF Sensor to take advantage of AirRaid CAI and Throttle Body Spacer plus Exhaust Improvements (Resonator Delete H-Pipe) and this one fits the bill. Much smoother throttle response over stock MAF Sensor with no lag when getting on the throttle. Great addition to my 2015 GT with Performance Pack. You will be pleased with the superior performance of this MAF Sensor plus easy install.

      More accurate

      Fit was perfect. Easy to install. Seems like my A/F ratio is more active which means it's probably more accurate. Also, since I have installed the inlet air temp hauage reads closer to ambient temp on the dash. I can notice a little more smoothness at lower rpm while the motor is cold vs with the stock MAF sensor (after the CAI was installed felt a hesitation like Maybe more air was getting in than metered). I can't really say that I can feel the claimed 10 rwhp gain claimed
