What is the MM size on this MAF?

  • A previous question asks the same thing. The answer there was approximately 80mm for the opening size. I suspect it will be the same size as your stock unit.

    Better than stock

    I got it because mine was cracked. It doesn't do much of a difference. I do like its look. Thanks AM

    Perfect fit for my Mach 1

    Perfect fit and easy to install. I use K'n'N cold air intake that uses the shaker system. So when I recharged air filter, I replaced old cracked MAF with this exact fit replacement. Bolts right up and no modifications needed. Great product and fair price.

    sensor n housing

    easy to install. took less then 20 minutes. replaced the old one cause the old one had a crack on the plastic. like the hissing noise when pressing the pedal like its sucking in more air. would recommend if needing a replacement.

    After installing my new MAF I noticed a big difference in the throttle response...I also have an aftermarket air intake(kandn),bbk throttle body and a Diablo tuner. It's a great compliment to what I already had.

    Excellent Product!!

    I bought this MAF for my 2004 gt and noticed a noticeable gain! Took me maybe 15 minutes to put on. Very well made and looks clean. I would definitely recommend this product.

    Outstanding Replacement MAF!

    The MAF unit on my recently acquired 04 Mach 1 was not functioning correctly. Rather than pay out the nose for an OEM replacement, I visited American Muscle and found this unit. Install was simple and quick. I'd recommend unclamping the MAF unit while still attached to the air filter as it makes unbolting it from the filter much easier while outside the engine bay. Re-install was a snap and the MAF was a direct fit. My Mach 1 is now running smoothly and performing like it should. American Muscle does it again!

    Best Value Around

    Oh NO, the dreaded 'service engine soon' light comes on! Of course with our 'Stangs it's usually something emissions related in California. So after getting the code that led us to the MAF sensor it was a simple fix. Sometimes the old one just needs cleaning but this time it was dead. My mechanic quoted me $250 for a refurbed Motorcraft part. I told him I'd look for a less expensive new one because he doesn't know that AM exists. As it happens, this part was new to AM so I figured I'd give it a try and save $100. I paid for the install once the part came and it's worked flawlessly for a week now. There was actually a little improvement in overall performance and acceleration that was noticeable with the new part. As always, I couldn't be happier with AM.
