  • Correct replacement for my Ford F150
Bought to repair 2003 Ford F150... The truck has been running great since the day I changed the old for the new.

  • Holes was too small.
Didn't fit perfectly.

  • It still reads that this part is not working and screw holes had to be drilled out, too small.
Didn’t fix the problem, so I’m going to test the part to make sure it’s working. Also the screw holes had to be drilled out because they were far too small. I would try a different brand. I have a 2003 F150 and it wasn’t a simple replacement.

  • Mass Air Flow Meter Works Great
I have had this on for almost a year, and it works like new. The price was so right that I could buy it without knowing for sure if my old one was bad. Thanks to all who make it available at this price.
