01 Skunk2
Ultra-Series Intake Manifold
The Skunk2 Ultra-Series intake manifold is made from high-grade 356 aluminum alloy and features an all-new, three-piece design. This allows for easy disassembly, porting, and plenum volume changes through the use of a removable plenum and optional plenum spacers. The large 90mm throttle-body opening, 87mm velocity stacks, and smooth transitioning high-velocity intake runners ensure optimal airflow characteristics. The Ultra-Series intake manifolds are designed to be used with high-horsepower naturally aspirated or forced-induction setups and include a thermal manifold gasket to reduce heat soak.

| 10 Fluidamper Damper
10 Fluidampr
Performance Harmonic Damper
Harmonic balancers reduce destructive crankshaft torsional vibration, which is the end-to-end twisting motion that is naturally generated during each power stroke. They contribute to greater valvetrain and timing efficiency as well as reduce bearing, oil pump, and crankshaft wear. OE rubber harmonic dampers are limited to function within the narrow frequency range of stock operating conditions, however, if horsepower and torque are increased, the damper can overwork and suffer catastrophic failure. Fluidampr solves this issue with an inner inertia ring design that is engulfed in a specialized silicone. It dissipates heat well and immediately self-centers so it is free to be “shocked” by each torsional vibration. Fluidampr performance dampers are SFI 18.1 approved and race proven for more than 25 years.
