    No More Pegging. The SCT Big Air Mass Airflow Slot Style Sensor is great for modified and dyno tuned applications where the stock mass air meter "pegs" due to increased air flow.

    Supports Up To 825RWHP. This MAF meter supports 400rwhp - 725rwhp with Centrifugal Blower applications and 400rwhp - 825rwhp with Roots Blower applications, and requires dyno tuning for the best results.

    OEM Quality Calibration. SCT's Big Air MAF Meters feature OEM quality calibration for factory level drive-ability, repeated accuracy, and reliability.

    Not CARB Certified. This Big Air MAF Meter is not CARB certified at this time, therefore it is not legal for use in California or other states adopting California emission standards. Not legal for use on pollution controlled motor vehicles; intended for off road use only.

    Direct Bolt-on. This Big Air Slot Style MAF Meter from SCT is a direct bolt-on replacement for the 2005 to 2010 GT and GT500 Mustangs, and can also be used on earlier model Mustangs and Trucks when used with a dedicated housing or by welding on the appropriate flange to intake piping. Requires dyno tuning.

    Note: Includes Slot Style Sensor only; housing is not included.

        Will this work with a SCT tuner?

        • The SCT BA-5000 Big Air Slot Style MAF Meter will work with an SCT Tuner, however you will require a dyno tune.

        Hello, Will this mafsensor fit my shelby GT 500 2008? it has a complete kit from kenne bell with the mammoeth charger wit upgraded injectors, bigger throttle body, and a kenne bell tune.

        • This SCT BA-5000 Big Air Slot Style MAF Meter / Sensor is a direct bolt-on replacement for the factory housing. In order to function properly, it would need a new tune.

        Dyno tuning and bama tune? this says it needs a dyno tune from a shop. If i have a bama tuner already does getting a tune from the shop mean i will no longer need my bama tuner? and also does the dyno at the shop tune the car for the other mods i have like the bama tuner does?

        • Dyno tuning or a BAMA custom tune is required for this mass air sensor to work. If you already have a BAMA Tuner/Tune you are good to go - all you need is a new tune from a BAMA tuning specialist

        N/A or Boosted? Will this function with a naturally aspirated setup, or will it only work for boosted applications?

        • This for boosted applications only.

        SCT Flash Tuner I know it says it needs to be dyno tuned, and this is probably a blatantly obvious question, but will the SCT SF3 with a 93 race tune suffice to run this?

        • Unfortunately, the Race Tune wouldn't suffice. With the application this MAF Meter / Sensor is designed to accommodate, a Dyno would be needed to get the most precise and accurate tune possible.

            Needed this after my dunk session pegged my pmas sensor around 600 fwhp and prevented any further adjustments.

            Needed, and fits a V6 4.0L!

            Idles fine. Installs like stock. Does not need a tune. I needed this after my fuel map changes for my power adders Nitrous Express and T70 Turbo. See this blue 4.0 Mustang with AmericanMuscle products used on my YouTube videos under "$25 throttle body".

            It works

            Its a blow through design, not a draw through. It works for my turbo set up fine.

            Im not sure if it was bad or not . It may have been left out of the tune, or it was defective.

            Performance Upgrade

            I have a 08 Roush 427R with over 500bhp, I had problems with performance lag in high revs. Once the sensor was installed I felt the difference in the power delivery. The ride feels so much smoother. Very easy to install.

            Great for blow thru setup

            I used this on my 01 gt with a vortech. I had to build a new intake tube with a new mounting point and splice in a new pigtail for the wiring but it made tuning the car easy and the drivability great.

            SCT BA5000

            The BA5000 Worked well. Smooth MAF readings allowed the computer to adjust the Fuel to Air much smoother than the competitors. This is needed when boosting of 12 pounds of Boost with a 4.6L 3V
