Product Details

Part Number: HYB-BUN-01-TB2
Brand: Hybrid Racing
Color: Black
Size: 75mm

Increase airflow and upgrade throttle response with the Hybrid Racing HYB-BUN-01-TB2 75mm K-Series Throttle Body Bundle. Designed for Honda and Acura K-Series performance applications using RBC, RRB, RRC, and RBB intake manifold bolt patterns, this drive-by-cable throttle body provides a large 75mm bore for naturally aspirated and forced-induction builds.

The HYB-BUN-01-TB2 configuration combines Hybrid Racing's HYB-THB-01-05 75mm throttle body with an IACV plug, making it ideal for setups where the idle air control valve port needs to be blocked off. Hybrid Racing designed the throttle body around OEM Honda TPS geometry to maintain proper throttle-position calibration while incorporating upgraded materials and hardware for performance use.

Constructed from 6061-T6 aluminum, the throttle body features double-sealed roller bearings, dual stainless-steel return springs, and staked butterfly bolts for dependable operation. A thermal insulating gasket helps reduce heat transfer from the intake manifold, while the adjustable throttle rotor provides multiple cable mounting positions for different K-Series and K-swap configurations.

Intake Manifold Compatibility

The throttle body uses the compatible Honda K-Series manifold bolt pattern and does not require a separate throttle-body adapter when installed on these supported manifolds.

HYB-BUN-01-TB2 is particularly useful for drive-by-cable K-Series and K-swap builds, including properly configured:
  • Honda Civic EG K-swaps
  • Honda Civic EK K-swaps
  • Acura Integra DC2 K-swaps
  • Acura RSX applications
  • Honda Civic Si EP3 applications
  • Other K20/K24 builds using a compatible intake manifold and drive-by-cable configuration
Kit Includes
  • 1 × Hybrid Racing HYB-THB-01-05 75mm K-Series Throttle Body
  • 1 × IACV Plug
  • Thermal insulating throttle-body gasket and applicable throttle-body components/hardware
Important Fitment Note:
  • HYB-BUN-01-TB2 is specifically the 75mm throttle body + IACV plug bundle. Hybrid Racing also offers HYB-BUN-01-TB1 with a MAP plug and HYB-BUN-01-TB3 with both MAP and IACV plugs. This throttle body is intended for drive-by-cable applications and is not a direct replacement for factory drive-by-wire throttle bodies. On RRC intake manifolds, an appropriate idle-air block-off solution is required because the manifold does not provide the same idle-control arrangement.

Due to the manufacturer's price control policy, this item may be excluded from promotions and discounts
