Product Description

The Skunk2 309-05-0095 Pro Series Throttle Body is the largest K-series throttle body Skunk2 makes, bringing a 74mm bore to Honda K20A/K20A2/K20A3/K20Z1 engines in the 2002-2005 Civic Si and 2002-2006 RSX. CNC machined from billet 6061-T6 aluminum and finished in black hard anodizing, it eliminates the OEM coolant hoses for cooler operation and uses a uniquely designed pulley for smooth pedal feel.

It's designed to pair with the factory RSX PRB intake manifold or Skunk2's own Pro Series manifold; pairing with a 2006+ Civic Si RBC manifold requires an adapter plate. Manual transmission only, and aimed at K20-powered builds chasing maximum airflow at the top end.
