The Skunk2 Composite Fuel Rail for Honda's K-series engines is a high-performance upgrade designed to improve fuel delivery and engine efficiency. Constructed from a proprietary carbon-impregnated, aerospace thermo-polymer composite, this fuel rail is 33 percent lighter and 60 percent stronger than traditional aluminum models. It operates up to 100 degrees Fahrenheit cooler, providing better insulation from radiant and conductive heat transfer under the hood. The large 0.625-inch internal bores enhance fuel injector pulsation dampening, while the smooth interior finish and radius-cut injector outlets optimize flow characteristics. This innovative design eliminates sharp internal angles common in aluminum rails, supporting up to 1,200 horsepower and delivering gains of up to three percent during testing.
Designed for Honda K-series engines from 2002 to 2005 Civic Si and 2002 to 2006 Acura RSX models, this composite fuel rail is compatible with the factory fuel system and all fuel types, including alcohol. It serves as a direct replacement or upgrade to improve fuel delivery and engine performance in street and track applications. Installation is straightforward, with the rail fitting seamlessly into the existing fuel system. The kit includes the composite fuel rail itself, supporting high horsepower builds and enhanced throttle response. Ideal for enthusiasts seeking increased horsepower, torque, and heat insulation, this product offers a durable, lightweight solution for performance-oriented Honda and Acura engines.
