      Review & Installation Video

      The SCT Big Air 90-millimeter mass airflow sensor is available for any V8, Fox Body, or SN95 owner, with a Supercharged and custom-tuned setup that requires a bigger setup than the stock option. Now, this will be able to handle the bigger power that's coming in, thanks to your forced induction setup, and it'll definitely get rid of some pegging issues you may be experiencing. The installation, as you can imagine, extremely straightforward, one out of three wrenches on our difficulty meter. But we'll touch more about that later on. Now, if you're running that blower setup on your V8, you're probably already aware of that pegging issue I just mentioned. Now, pegging, if you're not fully aware, is basically the limit at which airflow can be read by your stock sensor, which basically puts a cap on how much power your motor can make. Now, with a blower setup, you're obviously shoveling air into your manifold. So it does require a bigger sensor, like this 90-millimeter here, which completely eliminates that pegging issue. Now, the 90-millimeter option, while eliminating that bottleneck, will hold anywhere between 400 to 725 rear-wheel horsepower on a centrifugal blower setup, and up to 825 horsepower on a Roots-style blower. Now, the stock mass airflow sensor has been known to start pegging around the 400 to 425 wheel horsepower range. So obviously, very big differences here. You're pretty much doubling the capacity of what your airflow sensor can hold. So if you're running that kind of power, or you plan on running that kind of power, this is definitely something you want to look into. So just about $200 gets you this sensor here, along with the housing, and in my personal opinion, a very well-worth it price and obviously a very necessary component to your engine bay if you're looking to run that kind of power. If you don't plan on running anywhere kind of north of 400, this is probably not going to be the one for you, as it can start to bog down an engine that doesn't need it. Keep in mind, this was specifically designed for the blower and already tuned applications. Once you have this on your vehicle, you will require a retune, so you want to make sure you're working with your tuner on timing. Because once you get this thing on, you'll have to have a tune ready to go. The install, as you can imagine, extremely straightforward stuff. All you'll need is a ratchet and socket set, and a flathead screwdriver, and about 30 minutes or so in the driveway. I'm definitely giving this one a one out of three wrenches on our difficulty meter. The first thing you want to do is disconnect the wiring harness from the factory sensor, and then use your ratchet and socket set to unbolt the housing from the cold air intake setup. From there, you can swap over to the other side and use a flathead screwdriver to unclamp the housing from the coupler. Remove that completely from the engine bay, swap it out with the SCT one, replace those bolts, plug in the harness again and tighten up the coupler, and you're good to go. If you're the owner of a V8, Fox Body, or SN95, you might want to check out the SCT Big Air 90-millimeter mass airflow sensor/meter, which is available right here at

      • Requires Dyno Tune
      • Not CARB Certified


      No More Pegging.The SCT 90MM Big Air Mass Airflow Sensor is great for modified and custom tuned applications where the stock mass air meter "pegs" due to increased air flow.

      More Power. Specifically designed for supercharged applications the SCT BA-3000 Big Air 90MM MAF can handle much more power than the wimpy stock units. The SCT BA-3000 MAF supports 400rwhp to 725rwhp on Centrifugal Blower applications, and 400rwhp to 825rwhp with Root Style Blower applications.

      Application.The SCT BA-3000 90mm Big Air MAF is a direct bolt-on replacement for the 2000-2004 Ford Lightning and the 2003-2004 SVT Cobra. And it can also be used on supercharged 1989 to 2004 GT and Mach 1 Mustangs.

      Technical Note. The SCT BA-3000 Mustang Big Air 90MM MAF Meter requires custom dyno tuning for the best results.

        I recommend

        I’ve been looking at items that I can add to my Cobra that will give me some hp and won’t break the bank. With the tune from Bama, I defiantly felt the difference between the stock and this one. I am happy with my purchase.

        no more pinging the maf

        plugs in as it should just be sure if you plan on running an aftermarket filter to get the big filter bracket or else your aftermarket filter will not work.

        Air Aid

        My 03 Cobra is in the 650whp range. I was using an SCT BA2600 MAF Meter and decided to see if upgrading to the BA3000 would help my Terminator breathe better. After adding the new sensor(and a high flow air filter), I calibrated my tune(SCT Livewire TS) for the bigger maf sensor and air/fuel intake. Definitely made a difference! Overall performance and smoothness of acceleration have increased. I highly recommend the Big Air 3000 to those of you with higher power applications like mine or better.

        Big Air MAF Meter

        I found the product difficult to install. I was told in the ad that I had to use their tuner. Upon trying to get a tune I was told it wasn't for aftermarket supercharger. So I had to scrap the whole project. I'm looking for a tuner and Maf air meter to tuner my engine.

        Great product

        Does exactly as it should, works well on my 03 Cobra making 800rwhp. My Tuner suggested the sct maf over other makes due to the easy tunability.

      Will this maf meter work on the V6 mustang?
