The Hybrid Racing big bore K-series throttle bodies are by far the most feature packed throttle bodies on the market. When HR designed this throttle body, they wanted to create a reliable product that allowed as much flexibility in your setup as possible.

One simple, but very notable feature of this throttle body is the dual bolt pattern. By incorporating two bolt patterns, this throttle body is able to bolt directly to a PRB or RBC intake manifold. By eliminating the need for an adapter when upgrading from a PRB to RBC intake manifold, this throttle body saves you as much as $75. Another great feature on this throttle body is the ability to delete or retain your factory cruise control. This is the only big bore throttle body on the market that allows you to retain cruise control. Who says you can’t make serious power AND keep your creature comforts?

In the spirit of making this throttle body the most setup-flexible on the market, HR incorporated integral block-offs for the IACV, Emissions Solenoid, and MAP sensor. The IACV can be completely blocked off using the four included 1/8 NPT plugs. The Emissions Solenoid and MAP Sensor can be blocked off using the included aluminum plugs. Better yet, the aluminum plugs can be held down using the supplied retaining rings, meaning no worries of plugs popping out if you’re running boost! This throttle body also retains the IACV coolant port that many manufacturer’s hastily delete. This means that on K-swaps where radiator/IACV clearance is an issue, you can still rotate your IACV 180° and loop the coolant hose to eliminate the interference with the radiator while keeping the smooth idle offered by keeping the IACV.

Hybrid Racing throttle bodies are available in 74mm and 70mm bores with a 76mm inlet. The proprietary knife-edged 76mm inlet design means increased inlet velocities and lower inlet turbulence compared to competing throttle bodies. They feature dual ball bearings, dual needle bearings, integral O-ring seals, 6061-T6 aluminum construction, and a no-stick butterfly design. Each throttle body is supplied with stainless steel mounting hardware for all sensors and the throttle body itself. The kit also includes a custom fit thermal insulating gasket to help you keep intake temps down.
