The 3.5" Slot Style Pro-Tube is a universal mass air meter for "Blow Through" applications. It simply becomes a part of the duct work between the supercharger (or turbocharger) and the throttle body. The 3.5" Slot Style Pro-Tube features welded construction (no cheesy rivets!). The ends are bead rolled for a positive seal.
