Description:
This is the throttle body that opened up the K-series airflow game — and it's back, reengineered even better than before. After years of being the go-to upgrade for K-series enthusiasts, Hybrid Racing brought this throttle body back from the dead by popular demand, refined with real improvements over the original.
Precision-machined from 6061-T6 aluminum, this is a direct bolt-on for RBC, RRB, RRC, and RBB intake manifolds — a full 75mm inlet, opened up by designing specifically for this bolt pattern instead of being limited by the smaller PRB pattern. The IACV port has been rotated for better clearance between the radiator and wiring harness, and the TPS mount now mirrors the OEM Honda design for precise calibration with your engine management. Three cable mounting positions make it compatible with K-swapped EG, EK, DC2, RSX, and EP3 applications, and it pairs seamlessly with Hybrid Racing's HYB-TRC-01-05 and HYB-TRC-01-10 throttle cables.
Important: this is a drive-by-cable throttle body only — it will not fit the donor cars that many RBC-style manifolds originally came from. If you're installing on an RRC manifold, you'll need the IACV block-off plate (sold separately), since that manifold has no idle air control capability.
But this isn't just about a bigger bore. It's about a K-swap that actually breathes the way it should — the difference between a stock-feeling throttle and one that responds the second you get into it. Whether you're staying naturally aspirated or building boost, this throttle body does exactly that.
