85MM MAF SYSTEM FOR 02-04 MUSTANG GT OR MACH 1 In 2002, Ford completely redesigned the mass air flow unit for the Mustang. The new unit continued to measure in at 80mm but with an integrated air temperature sensor and different flow characteristics. Through dyno testing and the development of an all-new replacement MAF housing, we were able to introduce a new MAF package for 2002+ Mustang GT vehicles. Similar to our popular kits for the 1996-2001 Mustangs, our new kit #10699A comes complete with a new 85mm MAF housing, K&N air filter assembly and plastic shield to hold the assembly in place and draw cold air in from the fender. Dyno testing has shown this package to consistently deliver an average increase of 9 HP from 3000 RPM to redline with an average torque gain of 9, and a peak horsepower gain of as much as 14 between 5500-5700 RPM. The 85mm unit used in this package can not be used with earlier model vehicles. Due to the fact that the new sensor uses a different style electronics module, larger than stock injector sizes must be accommodated through a computer upgrade in the same manner that all supercharger systems utilize for 1999 and new GT Mustangs.
