The Skunk2 Composite Fuel Rail for the 2006–2011 Honda Civic Si with K20Z engines delivers enhanced thermal insulation, flow capacity, and fuel system performance. Constructed from a proprietary carbon-impregnated aerospace thermo-polymer composite, this fuel rail is 33% lighter and 60% stronger than aluminum alternatives—and operates up to 100°F cooler.
Designed to insulate fuel from engine bay heat, this composite fuel rail helps maintain consistent fuel temperatures and pressure, resulting in improved horsepower and torque. Its large 0.625-inch internal bore offers excellent pulsation dampening and optimized flow, aided by precision-machined, radius-cut injector outlets.
Compatible with all fuel types, including alcohol-based race fuels, this unit includes a specific fuel line connection kit for the 2006–2011 Civic Si, ensuring proper installation with the factory fuel system.
