LS3/LS7 Card Style Mass Air Flow with Weld In Bracket

This is a Card Style mass air flow that is found on newer GM V8 Cars.  This is the mass air that BP Automotive supplies with all of our Gen 4 Controller kits.  It is also the mass air flow that BP Automotive recommends to run if you are swapping a Gen 4 engine or for an Boosted LS engine that you are swapping.  It will not max out quickly under boost like other mass air flows.

The tuning in your PCM/ECM MUST match the mass air flow you use
