Product Overview
The K-Tuned 72mm Drive By Wire Throttle Body (part number KTD-72D-RBC) is designed for enhanced airflow management on select Honda and Acura models. Specifically engineered for the 2006–2015 Honda Civic Si, 2006–2009 Honda S2000, 2013–2015 Acura ILX, and 2009–2014 Acura TSX, this throttle body offers a significant increase in bore size for improved engine breathing.
The K-Tuned 72mm Drive By Wire Throttle Body is a direct bolt-on replacement for RBC and RRC manifolds and others sharing the same bolt pattern. Featuring a true 72mm machined bore and a brass butterfly, the K-Tuned 72mm Drive By Wire Throttle Body replaces smaller stock throttle bodies to allow greater airflow into the engine. The unit retains the OEM connector for seamless integration with factory wiring, maintaining a clean, factory-like installation. Two 1/8 NPT vacuum ports on the underside provide connections for evaporative emissions, brake booster, or vacuum reference lines. The inlet accepts a 3" silicone coupler, which may require adjustment to fit specific intake setups.
K-Tuned 72mm Drive By Wire Throttle Body Performance & Benefits
Compared to the stock throttle bodies, the K-Tuned 72mm Drive By Wire Throttle Body offers a 44% larger bore than the 2006–2011 Civic Si unit, 27% larger than the J35 throttle body, and 9% larger than the ZDX/J37 throttle body. This increase in diameter reduces airflow restriction, supporting better throttle response and potential power improvements when combined with appropriate engine management. The machined bore and brass butterfly ensure durability and smooth operation under demanding conditions. Inclusion of vacuum ports enhances versatility for various engine setups requiring vacuum sources.
Application & Installation of the K-Tuned 72mm Drive By Wire Throttle Body
Intended for use on the 2006–2015 Honda Civic Si, 2006–2009 Honda S2000, 2013–2015 Acura ILX, and 2009–2014 Acura TSX, the K-Tuned 72mm Drive By Wire Throttle Body requires FlashPro or compatible engine management software to recalibrate for the increased airflow. It is a direct bolt-on to RBC and RRC manifolds with matching bolt patterns. Installation should be performed by a professional or an experienced technician familiar with drive-by-wire systems and ECU tuning. The included thermal gasket, mounting bolts, and vacuum port plugs facilitate straightforward assembly. Note that the intake coupler may need modification or replacement to fit your specific intake configuration.
