Improves Airflow and Horsepower. The stock factory Mass Air Flow Meter (a.k.a. MAF for short) is only 55mm and flows a weak 550 cfm, where as the BBK MAF is 76mm and flows well over 700cfm to produce up to an additional 15hp at the rear wheels.
Pre-calibrate. This BBK 76mm Mass Air Meter Housing is already calibrated for use with 24lb fuel injectors saving you time and frustration.
Application. The BBK Performance 76mm Mass Air Meter is specifically designed for use in the 1986 to 1993 5.0 EFI Mustangs with 24lb fuel injectors and the stock factory airbox installed.
Technical Note. Mustangs with a BBK 1556 Cold Air Intake installed will use BBK 8001 or 8003 Mass Air Meter calibrated for a Factory Air Box.
