Skunk2 Composite Fuel Rail Choose Vehicle:Ultra Race B-Series Secondary 625+ material is substantially strongerSkunk2s cutting edge fuel rails are available in two materials aluminum and composite. Composite fuel rails are made using a proprietary carbon impregnated, aerospace thermo polymer compositea material thats 33 percent lighter, 60 percent stronger, and operates up to 100F cooler when compared to aluminum and insulates fuel from both radiant and conductive heat transfer underneath the hood, resulting in increased horsepower and torque.
