The Skunk2 Racing 72mm Electronic Throttle Body (ETB) for the 06-11 Honda Civic Si is an easy solution for increasing the airflow your Honda K Series engine needs to make more power. The Skunk2 72mm ETB flows 50% more air than the restrictive 64mm OEM throttle body. The 72mm ETB improves the throttle response and efficiency of both naturally aspirated and boosted engines.

Skunk2 ETBs are CNC machined from billet 6061-T6 aluminum. Our ETB’s feature a precision-honed oversized bore, high-torque servo motor, and an advanced Hall Effect TPS sensor. To ensure the best performance, throttle response, and drivability the TPS sensor is programmed to meet the specific requirements for each vehicle application. Skunk2 ETBs come with all necessary hardware and a Skunk2 thermal gasket for easy Bolt-On Plug-N-Play installation.

Features:

  • 50% Increase in Airflow Over Stock 64mm Throttle Body
  • Improved Throttle Response
  • Increased Power Output
  • CNC Machined Billet 6061-T6 Aluminum Body
  • Precision Honed Oversized 72mm Bore
  • High-Torque Precision Servo Motor
  • Advanced Hall Effect TPS
  • Thermal Gasket Included
  • Simple Bolt -On Installation
  • All Necessary Hardware Included

Skunk2 ETBs are not modified OEM units and do NOT require swapping electric motors.

Due to the larger size of the throttle body the factory intake tube will not fit.  We recommend the Skunk2 ETB to be used in combination with an aftermarket intake.  If your intake system is made from 3” tubing, we recommend the Skunk2 Racing 3.15" to 3.00" coupler. Part Number (943-05-0100).

SUPER great denim-should last for years!
Size: 30, Color: Truest Blue
lI don't know if these will be flattering on me, but I LOVE THEM. They're hip and cool and I will wear them although I am 65. Would look best with shorter shirts, but of course, not showing belly. A slim young woman would "kill" this look. Denim is heavy duty and all hardware top class. The ad said to size down, but I ordered my regular size. The waist is a little tight on me, but the barrel legs are loose and hang nicely. Definitely something I will wear with platform ankle boots or sneakers. I anticipate people will absolutely love them (younger folk) where people my age, may say hmmm because they are a statement piece.
