No More Pegging. The MAC Performance 73MM Mass Air Meter Sensor is great for modified and custom applications where the stock mass air meter "pegs" due to increased air flow.

Improves Airflow and Horsepower. The stock Mass Air Flow Meter (a.k.a. MAF for short) is only 55mm and flows a weak 550 cfm, where as the MAC MAF is 73mm and flows well over 700cfm to produce up to an additional 8hp at the rear wheels.

Pre-calibrate. This MAC 73mm Mass Air Meter Housing is already calibrated for use with 19lb fuel injectors saving you time and frustration.

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.

CARB Certified. Best of all this MAC Mass Air Meter is 50-state smog legal under Carb EO# D-241-7.

Application. The MAC Performance 73mm Mass Air Meter is specifically designed for use on the 1986 to 1993 5.0 EFI Mustangs with 19lb fuel injectors installed. Fits with either the the stock airbox or a MAC Air System installed. Reuses stock electronics.

Fitment: 1986 1987 1988 1989 1990 1991 1992 1993 Details

i purchased this MAC 73MM MASS AIR METER FOR 19LB INJECTORS (86-93 5.0L) but need a sensor for 19lb injectors. I am converting my 86 5.0 to maf. What sensor should i get?

  • Unfortunately we do not carry just the sensor. American Muscle only offers the Mass air Meter sensors with the housing or just the housing alone.

mounting Does this MAC mass air meter mount to the strut tower the same way as the factory one does, with an L bracket?

  • I took that bracket off years ago when I added the cold air (BBK 1557). There were no holes on the bottom for the bracket.

    MAC 73mm Mass Air Meter Rocks

    This thing was simple. It works great really noticed the increased range of acceleration. Can't wait to put more power parts in my Fox.

    nice product

    One small problem. No instructions. You can mount the meter either way. Proper way is opposite oem. Oem inner taper towards throttle body. Mac inner taper towards air filter. Mustang model LX
