  1. Skunk2 Composite Fuel Rail

    Skunk2’s 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 composite—a material that’s 33-percent lighter, 60-percent stronger, and operates up to 100°F cooler when compared to aluminum and insulates fuel from both radiant and conductive heat transfer underneath the hood, resulting in increased horsepower and torque. Composite Fuel Rails also feature large 0.625-inch internal bores for superior fuel injector pulsation dampening, are machined with a smooth interior finish, and feature radius-cut fuel injector outlets for improved flow characteristics. The all new aluminum fuel rails are are made from 6061T6 aluminum, a material that possesses an ultimate tensile strength of at least 42,000 psi (300 MPa) and yield strength of at least 35,000 psi (241 MPa). Skunk2's all new fuel rails feature large 0.669-inch internal bores for superior fuel injector pulsation dampening, are machined with a smooth interior finish, and feature radius-cut fuel injector outlets for improved flow characteristics. Skunk2’s B-series fuel rails can support up to 1,200hp, with gains as high as three percent realized during testing. Learn More

  2. 4P CNC Porting for Skunk2 Ultra Manifold

    If you have already purchased a Skunk2 Ultra Race or Ultra Street manifold, you can send it to the address below to be CNC Ported. 4 Piston Racing CNC Ported runners flow 50-70 CFM more air than an off the shelf manifold depending on the port profile. These ports are designed to be port matched to our race winning CNC ported cylinder heads. Please included your contact info and what engine you have in the box with the runners. Ship the manifold runners to: 4 Piston Racing 200 Colin Ct. Danville, IN 46122 317-440-6777 Learn More

  4. 4P Thermal Gasket

    4P Thermal Gaskets are cut to match our CNC Ported heads. These thermal gaskets reduce heat transfer from the cylinder head to the intake manifold. They are durable and can be cleaned and reused over and over. They will not shrink, warp, or melt at temperatures up to 500 degrees.

    • Port shapes precut to match 4P CNC Cylinder Heads
    • Reduced heat transfer from head to induction
    • Reusable
