Overview

The K-Tuned 72mm Drive By Wire Throttle Body is a direct bolt-on upgrade for specific Honda and Acura models. It features a true 72mm bore, which is larger than many stock throttle bodies, including the ZDX throttle at the butterfly. This increased airflow requires engine management, such as Flashpro, for proper operation.
Show original supplier description
The K-Tuned 72mm Drive By Wire Throttle Body offers a significant airflow increase for performance-oriented Honda and Acura vehicles. Designed as a direct bolt-on, it fits RBC/RRC manifolds and others with a compatible bolt pattern, featuring a true 72mm bore that is 44% larger than the stock 2006-11 Civic Si throttle body and 9% larger than the ZDX/J37. Constructed with a machined 72mm bore and a brass butterfly, this throttle body uses an OEM connector for an integrated look without the need for a jumper harness. It includes two 1/8NPT vacuum ports for applications like evap, brake booster, or vacuum reference. A thermal gasket, mounting bolts, and two 1/8NPT plugs are provided. The inlet is designed for a 3" silicone coupler, which may require modification to match your existing intake setup. Installation of this throttle body requires engine management, specifically Flashpro, to effectively manage the increased airflow. Calibration instructions are available and recommended for optimal performance and drivability. This throttle body is compatible with the following applications: 2006-2015 Honda Civic Si, 2006-2009 Honda S2000, 2013-2015 Acura ILX, and 2009-2014 Acura TSX.
