For years, Hybrid Racing's K-Series throttle bodies have been the go-to upgrade for enthusiasts looking to maximize performance. Since production ended, demand has only grown—and they heard you loud and clear. Now, Hybrid is bringing back their industry-leading design, refined and reengineered for even greater performance and reliability.

The latest version stays true to its winning formula while introducing key improvements. The new RBC Throttle Body is a direct bolt on for the RBC/RB/RRB intake manifolds. However, this throttle body is only designed for Drive By Cable, so it will not fit the donor cars that many of those manifolds come from. Hybrid rotated the IACV port to improve clearance between the radiator and wiring connector, ensuring a cleaner, more efficient installation. The TPS mount now mirrors the OEM Honda design, guaranteeing precise throttle position sensor calibration for seamless integration with your engine management system.

Precision-machined from 6061-T6 aluminum, this throttle body is built for the RBC, RRB, RRC, and RBB bolt patterns. By designing it specifically for these intake manifolds, Hybrid has eliminated the constraints of the PRB bolt pattern, allowing the inlet to a full 75mm. Whether you’re running a naturally aspirated or forced induction setup, this throttle body delivers the airflow your engine needs. It’s also designed to work perfectly with 3-inch couplers, ensuring a secure and optimized intake path.

To install the throttle body on the RRC Manifold, you must use the IACV Block Off Plate ( HYB-ICV-01-04 ) as the RRC Manifold does not have an idle air control ability.
