Skunk2 Carbon Composite Fuel Rail - K-series

Skunk2 Carbon Composite Fuel Rail - K-series

Skunk2 new cutting-edge composite fuel rails are made using our proprietary carbon impregnated aerospace thermo-polymer composite. This material insulates the fuel from both radiant and conductive heat transfer under the hood. Keeping the fuel cooler results in an increase in horsepower and torque. We have seen power gains of up to 3% in real world testing. 

Skunk2 composite fuel rails feature a large 0.625” internal bore with radius inlets to the injectors thus improving flow characteristics. This type of radius injector inlet design is not possible with extruded and drilled aluminum fuel rails (which have sharp angles internally where the main bore meets the injector bores).


  • Can be used with factory fuel system, lines, and fuel regulators
  • Up to 3% gain just by keeping fuel cooler
  • -8 AN end threads with 0.625" internal bore
  • Can support up to 1200HP
  • Chemical resistant to all fuels including alcohol

Vehicle/Engine applications: 02-05 Civic Si (K20A3), 06-11 Civic Si (K20Z3), 02-06 RSX Base (K20A3), 02-06 RSX Type-S (K20A2/Z1), 04-08 TSX (K24A2). Also compatible with K-swapped 88-00 Civic/CRX, 90-01 Integra vehicles.
