Skunk2 Alpha Throttle Body – B/D/F/H-Series – 66mm

The Skunk2 Alpha Series 66mm Throttle Body is designed to deliver maximum airflow and power gains across the entire RPM range for Honda B-, D-, F-, and H-Series engines. Precision-engineered and competitively priced, it offers a perfect balance of performance, reliability, and fitment versatility — making it an ideal upgrade for both street and race applications.

Constructed from precision die-cast aluminum with a fine shot-blasted finish, the Alpha 66mm throttle body ensures exceptional quality and durability. It features sealed ball bearings for smooth throttle operation, a CNC-machined brass throttle plate, and integrated idle adjustment screws for fine-tuning. The design promotes smoother airflow and improved throttle response, supporting both naturally aspirated and forced induction setups.

For best results, pair this throttle body with a Skunk2 Pro Series Intake Manifold. Some modification to the intake manifold flange may be required to match the bore diameter and maintain IAC passage separation.
