No More Pegging. The MAC Performance 85MM Mass Air Meter Sensor is great for modified and custom applications where the stock mass air meter "pegs" due to increased air flow.

Pre-calibrate. This MAC 85mm Mass Air Meter Housing is already calibrated for use with 19lb fuel injectors saving you time and frustration, so no tune is required unless you have made major mods or have installed larger injectors.

Billet Aluminum Housing. CNC machined to exact specifications from high quality 6061 T6 billet aluminum for accuracy, this MAC Performance Mass Air Meter Housing is polished to a bright brilliant shine for impressive under hood styling.

Application. The MAC Performance 85mm Mass Air Meter is specifically designed for use on the 2002 to 2004 GT Mustangs with 19lb fuel injectors. Fits with either the the stock airbox or a MAC Air System installed. Reuses stock electronics.

      What's the best MAF for me? My 02 GT was spitting and sputtering so I figured it was time to change the MAF. When I went to remove the screws they didn't release from "barrels inside". They stripped out so now I have nothing to fit the housing. I want to replace the housing. What MAF will best suit my mods?CAI, stock injectors, BBK long tubes, 4.11 gears, 5spd, BBK 75mm throttle body, intake spacer. I have bama tunes for life with my SCT tuner. I purchased the tuner after all the mods were made and run at the 93 tune.

      • Hi, I recommend the BBK 86mm Mass Air Meter for Cold Air Intake and 19lb Injectors Item #387000 over this MAC 85mm Mass Air Meter for 19lb Injectors since it sounds like you cant transfer your factory MAF sensor to this mass air housing, the BBK 86mm Mass Air Meter includes a new electronically calibrated MAF Sensor.

          Easy to install and also looks good, should make a good improvement over any stock options and better than other ones on the market

          Not recommended!

          This item caused my engine check light to come on constantly. Engine is stock with a BBK 78mm throttle body and cold air intake. Code kept saying air/ fuel mixture, which back to stock problem solved. Not sure why it didn't work properly.
