Description
Flows More Air. AmericanMuscle now offers the Ford Racing 90mm Lightning Mass Air Meter. The Ford Racing 90MM Mass Air Meter is great for modified and custom tuned applications where the stock mass air meter "pegs" due to increased air flow.

Application. This 90mm MAF from Ford Racing is a direct bolt-on replacement for 2000-2004 Ford SVT Lightning and will also fit the 1996-2004 GT, Cobra, and Mach 1 Mustangs, but will require custom tuning for proper results. Features:
  • 90MM MAF
  • Fits 1996-2004 GT, Cobra, and Mach 1
  • 4 Pin Connection
  • Requires a custom tune
Technical Note. This MAF sensor will need some wiring adjustments for it to work properly on the 2002-2004 GT, Mach 1 and SVT Cobra Mustangs. These models have the Intake Air Temp (IAT) sensor built into their stock MAF while this Lightning MAF does not. An external IAT sensor needs to added into the intake tubing.

Fitment: 1996 1997 1998 1999 2000 2001 2002 2003 2004 Details

best bang for the buck out there in an upgraded maf, as you increase performance, pegging your maf at 5 volts, the motor will go lean. And that’s bad emmm-k. Generally speaking the stock maf is good ...

What injectors? Is this calibrated to 42lb injectors?

Answer This Question I need this answered (0) (0)

Does this Mass air meter require larger injectors? I have a 96 Cobra with a C&L 80mm mass air, BBK twin 62mm throttle body, cold air intake and stock 24lbs injectors/fuel system. With an upgrade to this mass air meter is an injector change or fuel system upgrade needed to see the benefit of the larger mass air meter? I have no plans for power adders, or building the motor up, just looking for some showoff power and torque numbers, and enough gettyup to do something stupid with.

    ford racing 90mm maf.

    best bang for the buck out there in an upgraded maf, as you increase performance, pegging your maf at 5 volts, the motor will go lean. And that’s bad emmm-k. Generally speaking the stock maf is good to about 300 hp, the 80mm maf 350-375, ish and the 90mm lighting maf will peg around 450 hp. Its best to size your maf a bit larger than intended hp, but not too much, as you give up resolution, you still only have a 5 volt max to the ecu. NOTE, Any Ford MAF as well as the SCT MAFs are NOT calibrated for any injector size. The injector size is set in the ECU. I have found, as well as other smarter than me, that this ford racing 90mm maf will make a great smooth transitions with 4" air cleaners and ram air or cold air intakes such as jlt, and the bbk 79mm throttle body/pethum it will neck down to 3" increasing velocity into the intake manifold. this set up has been used to good effect in many motors. Absolutely requires a tune, mass air transfer function is about the most important part of the tune.

    Awesome

    This combined with the BBK Twin 65mm Throttle Body gave my 98 Cobra SOOOO much more low end torque!! This definitely lets the engine suck in a whole lot more air!

    Awesome

    I installed this MAF with the BBK 65mm throttle body on my 2001 Bullitt, the low end is awesome. Much better throttle response too.

    90mm lightning meter

    Make sure to get 39lb/42lb injectors with this product otherwise it's worthless to buy, you should also get the throttle body upgraded too, I had a performance shop install it & Dynotuned my car, no major gains maybe 4-5hp

    TRUE LOW END TORQUE GAINS CRISPER RESPONSE

    I really don't know where to begin. I have a mildly modded 00' GT ALL BOLTONS comp cams 270's and 125 shot of nitrous. After the install the response of the thottle was very much improved and noticeable. Although tuned by BAMA, my rpm's were set at 770 so my car would drop too low in rpm's to where it would shut off when idling. This was ok because I know my car and am familiar with the SCT tuner so I simply reset my rpm's to 900 right where they need to be in order to keep the car at a nice steady idle. Tune is great and the 90 mm FR maf is truly worth every penny. Car makes 430 HP / 414 toque and putting down 355 RWHP to the wheels on a 125 shot of nitrous. The car now runs as it was meant to do. Very pleased with this lighting maf and I recommend it to any 4.6L owner who's modified their car.

    90 mm lightning MAF

    it was a bit of a pain to install, needed a bigger sleeve to attach the intake to it. but overall good quality upgrade for your stang I don't think this improves overall horsepower but I definitely feel a quick response from the throttle, I'd equate this gain similar to when I first installed my new throttle body. so I'm pleased.

    Every mustanger owner should get this!

    My old mafs had a crack on the top so I end up replacing it with this one. Ended up with a way better response time and gain about 5hp after tuning my car. Great product, worth the money and very fast shipping, thank you american muscle.
