This is our plug and play Flex Fuel Kit for the Honda Civic Type R (FK8).   In our opinion, the best upgrade to your FK8 is better octane fuel, and increasing the Ethanol content of the fuel your engine sees is the easiest and best way to see power gains with your FK8.

Our kit features all new components, a genuine GM sensor, KTUNER flex converter box, Race Spec wiring harness and a braided stainless low pressure line with AN fittings.  The mount uses OEM mounting locations and a clean look.

Requires the use of a Hondata FlashPro for FK8 Civic.  Consult your tuner if you have questions on what you need to do.  We can offer limited support if you are not custom tuned just yet.
