Skunk2 Alpha Throttle Body – 74 mm – K Series

The Skunk2 Alpha Series 74 mm Throttle Body is engineered for high-performance Honda K-series engines. Designed to work with Skunk2 Pro Series intake manifolds (or with port-matching), this throttle body increases airflow and power while maintaining smooth idling and throttle response. Featuring a fine shot-blasted finish and precision machining, it’s built for both naturally aspirated and forced induction setups.

Key Features

• Precision die-cast aluminum construction

• Fine shot-blasted surface finish

• Precision-machined brass throttle plate

• Sealed ball bearings for smooth operation

• Dual bolt pattern compatibility: PRB/PRC and RBC/RRC

• Includes new throttle body gasket and mounting hardware

• Designed for use with Skunk2 Pro Series intake manifolds or properly modified manifolds

Fitment

Compatible with Honda K-series engines:

• K20 / K20A / K20Z

• K24 / K24A / K24V / K24Z

Important Notes

Because of its larger bore, this throttle body requires either:

1. A compatible Skunk2 Pro Series intake manifold

2. Port-matching or flange modification to maintain a proper seal and preserve IAC (Idle Air Control) passage separation
