Skunk2 Racing valve springs are made from the highest quality chrome silicone wire from Japan. These valve springs are designed from our experiences in touring car and drag racing. The dual interference fit valve spring design prevents harmonics and valve float. All valve springs are race tested and proven and can be used with both forced induction and naturally aspirated engines.

Adjustable cam gears allow engine tuners to optimize horsepower and torque by adjusting camshaft timing. All adjustable cam gears are CNC-machined from AL7075-T6 billet aluminum. The 6-bolt design eliminates any chance of slippage, while the hard-anodized finish prevents premature wear. The timing marks are laser-etched and each offer over +/- 10 of adjustment. Skunk2's cam gear design has been proven on race cars in the most extreme conditions, and has proven to be the most reliable cam gear on the market.

The most restrictive part of any induction system is the factory intake manifold. Knowing this, Skunk2 Racing went to great lengths to design and manufacture an appropriate aftermarket replacement. Skunk2 Racing manifolds are designed to maximize flow as well as increase the effects of wave scavenging at each engine's key operating RPM range. Each manifold is designed to use all the stock sensors and auxiliaries.
Some key features:

• Single-stage intake manifold design
• Significant mid to high range power gains
• CARB EO-pending

Skunk2 Racing retainers are CNC-machined from the strongest aerospace quality titanium and are designed to significantly reduce overall valvetrain mass. Skunk2 Racing retainers are machined to extremely close tolerances in order to ensure properly installed spring heights and pressures.

Skunk2 Racing valves are made from SAE EV8 stainless one-piece forgings, which are then heat-treated using a proprietary heat treatment process. After CNC-machining and swirl polishing, a PVD black nitride coating is applied to reduce friction and increase wear resistance. Skunk2 Racing valves are lightweight, durable, and offer excellent heat and corrosion resistance. Skunk2 Racing valves are available in standard and high compression styles and also in various sizes. Oversized valves should not be used with standard size valve seats or with Stage II and III VTEC camshafts.

Stage I: Stage I profiles are designed to offer the widest possible powerband and be compatible with factory valvetrain components. These camshafts are designed to retain stock idle and are currently CARB EO-pending. Upgrading to Skunk2 Racing valve springs is recommended. Stage I profiles are relatively easy to tune for maximum power output.
