Hybrid Racing 75mm RBC K Series Throttle Body w/ Map and IACV plugs

Engineered for Maximum Airflow & Fitment

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, we’ve eliminated the constraints of the PRB bolt pattern, allowing us to open up 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 as the RRC Manifold does not have an idle air control ability. 

Built for Durability & Smooth Operation

Reliability is at the core of our design. Each throttle body features staked butterfly bolts to prevent loosening over time, a crucial upgrade for long-term durability. To further enhance performance, we’ve included a custom-fit thermal insulation gasket that reduces heat transfer from the intake manifold, keeping temperatures in check for consistent throttle response. Inside, double-sealed roller ball bearings ensure a smooth, precise throttle operation without the risk of sticking.

Refined Throttle Cable Bracket & Adjustability

We didn’t stop at just refining the throttle body—our throttle cable bracket has also been improved for better fitment and longevity. Bent and welded from high-strength steel, we’ve zinc-plated it to resist corrosion and adjusted the length and angle to improve hood clearance in K-swapped applications. This means an easier install and a cleaner look under the hood.

For the best fitment and solution, make sure to use the Hybrid Racing Replacement Throttle Cables, HYB-TRC-01-05 & HYB-TRC-01-10. 

Versatile Fitment for K-Swapped Builds

Designed with flexibility in mind, the throttle body rotor offers three cable mounting positions, making it compatible with K-swapped EG, EK, DC2, RSX, and EP3 applications. It pairs seamlessly with HYB-TRC-01-05 and HYB-TRC-01-10 throttle cables. To ensure long-term reliability, we’ve also integrated dual stainless-steel throttle return springs—adding an extra layer of safety while eliminating the risk of rust.
