BLOX Racing 72mm Billet DBW Throttle Body - 2006-2011 Honda Civic Si

BLOX Racing's 72mm Drive-By-Wire (DBW) Throttle Body is a plug-and-play OEM replacement for the 2006–2011 Honda Civic Si, freeing your engine from the restrictive 64mm factory unit. No swapping electric motors, no wiring changes, no mounting adapters — just bolt it on and go.

Each unit is built new from scratch — not remanufactured — with a CNC-machined billet 6061-T6 aluminum housing, a high-torque servo motor, and a proprietary non-contact Hall Effect TPS sensor calibrated specifically for your vehicle's ECU. The result is improved throttle response, increased airflow, and better drivability on both stock and modified engines.
