Review & Install Video
Ford Performance's 90-millimeter Mass Air Meter is a great option for the '96 through to '04 two-valve owners out there that have more or less maxed out their current air intake setup with plenty of other air and exhaust mods like a cold air, intake manifold, throttle body, and headers. And, in my humble opinion, its huge MAF housing upgrade is really geared for forced induction applications.
But in terms of the installation here, guys, this is getting an easy one out of three wrenches in the difficulty meter here, less than an hour of work with basic hand tools as it's merely just gonna be replacing your existing setup.
So what exactly is this stack? Well, at face value, guys, it's a mass air meter, nothing nuts about that, and it's gonna go in between your air filter and your throttle body. But why would you want or, more importantly, need a bigger mass sensor? Well, the word "need" is key here, and, generally speaking, the stock MAF unit can only handle so much air. Now, when you've bought every other air and exhaust bolt-on available, or you're going forced induction, you're more or less adding too much airflow for the stock MAF unit, and that's where this upgrade comes in. And not only is airflow something that's key here, but having the right amount of fuel is another variable that you really need to pay close attention to. Your injectors will come into play here along with needing a tune, and, with that said, a tune is also really important here when installing this MAF unit, and this is something that we see our customers using with cars that are already being dyno-tuned. Now, either way, if you're the owner that's maxed out your naturally aspirated mods or you're looking into a turbo or a blower, this is going to be a must-have mod in order to avoid having your factory MAF pegged because of that increased flow.
So the requirements aside, guys, you're looking at a quality Ford Performance takeoff here, and now this same MAF sensor is found on the blown SVT Lightning, and it's made from a rugged injection-molded body, which is gonna help reduce heat soak, which can be common on heavily modded or blown cars.
Now, speaking of factory modification, this will need some wiring adjustments on the '02 through '04 GTs, the Machs, and the '03, '04 Cobra. Now, these models have the intake air temp sensor built right into the stock MAF. While this unit does not add an external IAT, it does need to be added so your ECU can look at the temperature to control timing accurately.
But in terms of the pricing here, guys, expect to be sweated just about 130 bucks for this unit, and that is gonna be one of the most affordable MAF meters in this diameter at the time of shooting this video. And it's a small price to pay considering you'd likely spend a ton of money under the hood of your car with this helping you get that extra bit of power when it counts.
Now, installation-wise, you're looking at a very straightforward one out of three wrenches on the difficulty meter here out of 30 minutes to an hour job. You will start with disconnecting the wiring harness for the factory sensor. You're gonna use the ratchet and socket set to unbolt the housing from your setup. Now, from there, swap over to the other side and use a flathead to unclamp the housing from the coupler. Now, you then wanna remove that completely and then swap it out with your Ford Performance 90-millimeter option. Replace the bolts, plug in your harness, tighten your couplers, and you're ready to go.
This set's gonna wrap up my quick review and breakdown of Ford Performance's 90-millimeter Mass Air Meter/Sensor fitting the 1996 through 2004 4.6-liter Mustang that can be found right here at americanmuscle.com
