Product Description

The Skunk2 309‑05‑1030 Alpha Series 66 mm Throttle Body is a performance‑oriented intake upgrade designed to increase airflow into a wide range of Honda and Acura engines (B‑Series, D‑Series, F‑Series, and H‑Series) when paired with a compatible intake manifold flange. Featuring a 66 mm bore, precision‑machined brass throttle plate, and sealed ball bearings, this throttle body improves throttle response and power potential on both naturally aspirated and forced induction setups. The die‑cast aluminum body with fine shot‑blasted finish provides durability and a refined engine bay appearance, while idle adjustment screws and OEM throttle cable compatibility make installation straightforward.

This Alpha Series throttle body is designed for use with Skunk2 Pro Series intake manifolds or other intake manifolds with a matching flange to maintain proper sealing and idle air control (IAC) passage alignment; some intake configurations may require manifold modification or an adapter to fit correctly. Ideal for high‑airflow builds seeking improved throttle efficiency and overall engine performance, this 66 mm throttle body delivers solid flow gains at a competitive price-point.
