      Product Information

      Features, Description, Reviews, Q&A, Specs & Installation


      • No More Pegging
      • Improves Airflow
      • 86mm Mass Air Meter Housing
      • Electronically Calibrated Mass Air Sensor Included
      • Pre-Calibrated for 24lb Injectors
      • CNC Machined Black Powdercoat Housing
      • Fits 1999-2002 GT Mustangs with Aftermarket Cold Air Intake


      No More Pegging. For modified and custom applications where the stock mass air meter "pegs" due to increased air flow, a BBK 86mm MAF with Sensor would be a great addition. By upgrading the stock 80mm MAF in your 1999-2002 Mustang GT, you can potentially unlock up to an additional 15hp at the rear wheels.

      Pre-calibrated. This BBK 86mm Mass Air Meter Housing is already calibrated for use with 24lb fuel injectors and an aftermarket cold air intake, saving you time and frustration by maintaining an accurate air/fuel ratio.

      Black Powdercoat Housing. CNC machined to exact specifications from high quality 356 aluminum, this BBK Performance Mass Air Meter Housing features a black powdercoat finish for impressive under hood styling.

      Application. The BBK 86mm Mass Air Meter is specifically designed for use in 1999 to 2002 GT Mustangs with 24lb fuel injectors and an aftermarket cold air intake installed.

      Technical Note. Not compatible with Cobra models as they require different calibration.

        Well, I bought this back in June 2017, Lang with 24lb ingectors and a Bama custom chip, Ininstall the MAF along with the Chip and started getting a lot of misfires and the car would idle really rough and cut off, I found out by accident that by disconnecting the sensor out of the MAF the car would idle like it supposed to. I put the old MAF back on and had no more issues and no more misfires, I read other reviews similar to mine and now I know it was just me. Not buying anymore BBK items

        I installed this last summer along with ford racing 24# injectors. My mustang never idled correctly even with a dyno tune. Installed an oem sensor and issue was gone. My stang now idles perfectly. This item was a waste of time and money

        I had ordered the BBK 86mm Mass Air Meter for my Ford Performance 24lb injectors. I had installed the injectors and the Mass Air Meter with a new BAMA tune. When I had started the mustang it throw codes and kept cutting off with a rough idle. A week later I had taken the car to two different shops and they could not find the issue because I had thought it was a fuel injector or fuel pump issue but is was not. I had replaced the mass air meter with the original air meter and the issues were gone no more codes, rough idles or stalling. I would not get another mass air meter from BBK.

        Terrible does not work if you already have an aftermarket tune. Throws all kinds of codes. I put the stock one back on and it's fine. And since I put it on the car they won't allow me to exchange or return.

        Check engine light came on after I put it on

        I hope my reviews helps some people out because I just about had enough of bbk junk. I bought there 78mm throttle body just as I'm sure a lot of people did and the pedal sticks after trying to give it gas from a dead stop look on forums everyone is complaining about it. Then over the weekend I install there 86mm mass air flow sensor and the check engine light comes on right away, but they tell ya that it comes pre tuned and is a simple 10-15 hp. Well I'm here to tell you it's not. Apparently I'll have to buy a bama tuner or take it to get tuned or something because the car isn't exactly running right. So I hope this is useful to people my opinion save yourself the headache. STAY AWAY FROM BBK PRODUCTS. They have given me nothing but grey hairs!

        Great performance part

        My old MAF was pegged out with my 24lb injectors and all my intake mods. This MAF really woke all my performance parts up. It's a great performance and cosmetic part. Highly recommend

      Could this be re-calibrated for a different injector size (ie. 60lb)?

      • The BBK 86mm Mass Air Meter for Cold Air Intake and 24lb Injectors has the calibration for the injector size built into the MAF assembly and would not be able to be re-calibrated.

      If this is already calibrated for 24lb injectors, why can't it be used on a 96-98 cobra since they already have factory 24lb injectors? Wouldn't a tune adjust any measurements needing to be adjusted since it's for 24lb injectors and the cobra is already equipped with 24lb injectors?

      • The BBK 86mm Mass Air Meter for Cold Air Intake and 24lb Injectors has the calibration for the injector size built into the MAF assembly, whereas the Cobra's have this part of the calibration built into the PCM. Swapping to a MAF calibrated for 24 lb/hr injectors in a GT would throw the calibration off in a Cobra, which is already set up for the 24lb/hr injectors in the PCM. We have not run the numbers for this used on a Cobra, but it would be essentially mean a final calibration over 24 lb/hr injectors on Cobra models.

      Cannot find MAF for v6 with 24lb. Injectors. If the plug connection is modified would this work for the v6 or would it be to much air?

      • The BBK 86mm Mass Air Meter would not be properly calibrated for the V6. To adjust for injectors, the easiest route for your setup may be to adjust via a tune.

      I have installed this MAF sensor with my new 24# injectors. My question is, can I also select 24# injectors in my canned SCT tune, or would it cause problems since this product is essentially skewing air flow reading to make the engine run fine wothout a tune. Thanks!

      • Since it is already calibrated, you will not need to select 24 lb injectors on your SCT tuner for the BBK 86mm Mass Air Meter for Cold Air Intake and 24lb Injectors.

      Will this work with stock inje toes on a 99 gt? If not can it be tuned to work using my sct hand tuner?

      • Hello! The BBK 86mm Mass Air Meter for Cold Air Intake and 24lb Injectors is pre calibrated for 24lb injectors. It cannot be tuned for stock injectors.

      01 GT manual trans: so if I install the BBk 86mm Mass air meter and 24lb injectors at the same time, will they work with each other (no check engine lights), and not require a custom tune? Currently I don't have a tuner installed. I do have a K N filter in stock intake(snorkel removed), 70mm throttle body, C L plenum, shorty headers, cobra mid pipe and magnaflow catbacks, with 3.73 gears. 1 answer
      Will I be able to use this with my 47lb injectors? Is it compatible with a tune or will this meter peg out? If not compatible what would you recommend to use with my injectors? Thanks for your time as always. 1 answer
