Will this fit on the chrome BBK cold air intake kit?


  • The MAC 73mm Mass Air Meter for 19lb Injectors (01-04 V6) will not fit with the BBK Cold Air Intake (99-04 V6). This Mass air meter will require the use of a factory air box or the Mac air system.

What is this product supposed to do exactly? Prevent certain codes, or just allow more air to come through without the ECU tripping out?


  • The MAC 73mm Mass Air Meter for 19lb Injectors will all more air to be measured in applications were airflow has been increased. Since the volume of the stock units are much smaller, they can only read the amount of air that can passed the sensor with their given volume. By increasing diameter, it directly increases the amount of volume that can be measured at a single given moment.

    A vital link in a V6 intake upgrade!

    If you've already put a CAI on your V6 Pony, and wondering WHERE the power increase is.... If you haven't also replaced the MAF - your higher flowing CAI is trying to breathe through the stock, tiny, 56mm MAF!! The Mac 73mm MAF housing reuses your factory MAF sensor - and really lets the REST of the intake upgrades you've done, WORK the way they were intended, giving you that Punch that you can FEEL!! Highly recommended!
