QFT hand builds its Dual Pattern Throttle Bodies "slabbed" throttle shafts (machined away for more flow) and Teflon® ribbon bearings for durability and superior sealing. The throttle plates are secured with low profile Torx® plate screws to help reduce air turbulence. These throttle bodies feature a unique adjustable secondary pump cam bracket that allows for secondary airflow adjustment. The QFT spacer plate (#300-4145-1AL) offers a smooth transition and is required for use on the large flange 4500-style intakes.

Each throttle body comes with an assortment of throttle links to easily change the opening ratio from soft progressive to medium progressive or 1:1. All attaching screws and gaskets are included.
