Skunk2 Pro Series Throttle Body – Honda K-Series (74mm)

The Skunk2 Pro Series 74mm Throttle Body is engineered for Honda K-Series engines (K20A, K20A2, K20A3, K20Z1, K24A, K24Z, and K24V), delivering exceptional airflow and throttle response for both naturally aspirated and forced induction setups. Designed to support high-performance applications, this throttle body provides a significant increase in airflow capacity—unlocking horsepower and torque across the entire RPM range.

Precision CNC machined from forged 6061-T6 billet aluminum, the Pro Series Throttle Body features a precision-machined brass throttle plate, sealed ball bearings, and a honed oversized bore for smooth, consistent operation under extreme driving conditions. The body is hard anodized for corrosion resistance and includes a new gasket and mounting hardware for a direct, reliable installation.

This throttle body retains compatibility with the OEM throttle cable and IACV (Idle Air Control Valve) circuit, making it an ideal upgrade for performance street or race engines.
