The Skunk2 Composite Fuel Rail for Honda B-Series engines is engineered for racers and performance enthusiasts seeking superior fuel delivery, strength, and thermal protection. Made from a proprietary carbon-impregnated aerospace thermo-polymer composite, this advanced material is 33% lighter, 60% stronger, and operates up to 100°F cooler than traditional aluminum fuel rails.
Unlike aluminum designs that can transfer excessive heat to the fuel, Skunk2’s composite construction effectively insulates against both radiant and conductive heat, keeping fuel temperatures lower and improving combustion efficiency. The result is enhanced horsepower, torque, and consistent performance under demanding conditions.
Designed with large 0.625-inch internal bores, the Composite Fuel Rail ensures superior fuel injector pulsation dampening and smooth, unrestricted fuel flow. Each rail includes integrated -8 AN inlet and outlet ports, OEM fuel pressure regulator provisions, and a 1/8-inch NPT fuel pressure port, offering full compatibility with both OEM and custom fuel systems. Tested to support up to 1,200 horsepower, this system is suitable for both pump and race fuels, including alcohol blends.
