Skunk2 – Alpha Series 70 mm Throttle Body

Skunk2 Alpha Series 70 mm Throttle Body

This high-performance throttle body from Skunk2 is designed for Honda/Acura B-series, D-series, F-series and H-series engines that demand improved airflow and throttle response. Featuring a 70 mm bore size, it dramatically expands the intake path to support modified naturally aspirated and forced-induction applications.

Constructed from precision die-cast aluminum with a fine shot-blasted finish, this throttle body includes a precision-machined brass throttle plate, sealed ball bearings to ensure smooth operation, and idle-adjustment screws for fine tuning. It is compatible with OEM throttle cables and comes with the necessary gasket and mounting hardware.

Applications:
Designed for manual-transmission vehicles equipped with engines from the B, D, F or H series (for example 92–00 Civic B-series, 94–01 Integra B-series) and other high-flow intake setups requiring enhanced airflow.

Installation Notes:
Due to the oversized 70 mm bore, it must be used with a compatible intake manifold (such as Skunk2’s Pro Series intake or equivalent) and is not compatible with down-flow intake manifolds or certain stock manifolds without modification. Proper tuning (TPS, idle control, ECU calibration) is required after installation to realise performance benefits.
