Product Description

Better Performance, More Power!
Get more power our of your 4.6L Mustang or 5.4L Lightning with this Ford Performance 90mm mass air meter! This mass air meter, or MAF, is is a stock replacement for 2001-2004 SVT Lightnings; as well as a great upgrade for 1996-2004 Mustang 4.6's. Ford Performance's 90mm MAF is perfect for Mustangs looking to get more power and performance when the stock MAF has pegged out. Ford Performance manufactures this mass air meter with a rugged, injection-molded body to reduce heat soak, which is a common problem with stock sensors.

Installation Note
-The MAF sensor will require some wiring for it to work properly on 2002-2004 4.6 Mustangs. These years have the Intake Air Temp (IAT) sensor built into their stock MAF while this Lightning MAF does not. An external IAT sensor needs to be added into the intake tubing.
-An aftermarket tune will be required when installing this MAF on a Mustang.

-Fits 2001-2004 SVT Lightning
-Fits 1996-2004 Mustang 4.6 w/ Custom Tune

5 Stars   ford racing 90mm maf.
By on 1/6/2017
Words of 2v, wisdom from an old man.
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. this ford racing 90mm maf will make a nice smooth transitions with 4" air cleaners like ram air or cold air intakes such as jlt, and the bbk 73mm throttle body/pethum it will neck down to 3" increasing velocity into the intake manifold. a gasket match on the intake and heads helps. a nice port job and a cam completes the intake side.
this set up has been used to good effect in many 2v motors. Absolutely requires a tune, mass air transfer function is about the most important part of the tune.
