Perfect fit, super fast install, and solved my problem almost instantly!
Size: 74-50011
I didn't realize how easy and quick this would be, and didn't understand how important it was to how well the car ran. I installed a cold air intake kit 15 years ago and just used the original MAF sensor, but over all those years, I'm sure it had been failing or underperforming. And recently I started getting notifications from ODBII testing that indicated the MAF was not quite at its best. When I ordered this one, it fit right in place just like OEM, and took less than 5 minutes to swap out (including finding my security torx bit to unscrew it.) I went for a drive and immediately could tell the difference in throttle response and perceived horsepower. I wish I had known to swap this out years ago! Especially as inexpensive as it was. I imagine anyone reading this review already has tested and discovered the need to replace it, so don't wait and just go for it! The reason I chose this particular one on Amazon was due to the higher ratings overall. There are so many that Amazon says fit my 2002 Mustang, and some cheaper, but this one in particular seemed to have the best overall reviews and was worth paying a few dollars more than the cheaper ones. ... show more

Good deal.

Time will tell, but so far so good. And if you consider the product warranty along with the price savings from a box store, this is a pretty good deal.

DO NOT PURCHASE! I learned the hard way that Mass Air Flow Sensors, especially on an old Ford Focus, are something you DO NOT want to cheap out on. After a month or two it started throwing P0171/2 errors that were hell to track down. It was only later that I realized the culprit was this cheap MAF. While quality mass air flow sensors do cost $100 on up, which does seem quite steep, they are worth it in the long run. Do yourself a favor and save up for a Delphi, NTK, or Motorcraft. A Delphi can be found for roughly $110 after tax. Bought this for my 2002 Ford Focus 2.0 SPI. ... show more
