K-Tuned's new 72mm DBW (drive-by-wire) throttle body is direct bolt on to RBC/RRC manifolds and others with the same bolt/flange pattern. It is a true 72mm bore which is larger than the Honda ZDX throttle at the butterfly. This throttle body requires some form of engine management (Flashpro or Ktuner) to properly manage the increased airflow. K-Tuned used the stock configuration and design using an OEM connector to avoid jumper harness. This gives it an almost OEM look when installed. Inside you will see the machined 72mm bore and brass butterfly. There are two 1/8NPT vacuum ports on the bottom which can be used for evap, brake booster, or vacuum reference. Included you will get a thermal gasket, mounting bolts, and two 1/8NPT plugs.

The inlet will use a 3" silicone coupler. You may need to change the coupler to match your intake.

How big is 72mm TB? K-Tuned did some measurements and compared it to other stock and common options. They measured the area at the smallest opening since this would be the bottle neck in the system:

K-Tuned 72mm DBW throttle body is..

  • 44% larger than K20Z3/06-11 Civic Si t/b
  • 27% larger than J35 series t/b
  • 9% larger than the  J37/ZDX t/b
Vehicle application: 06-15 Civic Si, 06-09 S2000, 13-15 ILX, 04-14  TSX
