Product Details

Part Number: KTD-CA8-35F
Brand: K-Tuned
Color: Black
Fitment Notes: ECU Tuner Required

K-Tuned has put together the most diverse and customizable 2006-2011 8th Gen Civic Si Intake Kit on the market. 

  • Start by selecting the proper throttle body velocity coupler to match the TB you are using. 
  • The velocity coupler provides a perfect transition from the piping to throttle body unlike standard silicone couplers.
  • Flashpro or KTuner is required and you'll have to switch over to a MAP based tune if you are using the 3.5" pipe. 
  • The Cold Air Intakes come with a K-Tuned K24 Upper Radiator Hose. 
  • We have also designed a special battery tray to move the battery down to the frame rail and make even more room. 
  • All the necessary hardware and clamps are included.
  • This option is for the 3.5" piping and regular sized filter, please select the throttle body coupler from above.
