GSC P-D 06-07 Subaru 2.5L WRX / 04-07 Subaru STi S3 Cams 282 Billet - (Right Exhaust Cam Only)

If you're looking to get more out of your Subaru's engine, especially if you're building a performance setup for your 2006-2007 WRX or 2004-2007 STi, a camshaft upgrade can make a notable difference. This is the GSC Power Division S3 camshaft, specifically designed for the right exhaust side of the 2.5L engine. It's a billet cam, meaning it's machined from a solid piece of steel, which is a strong way to build these components for better reliability under stress.

The S3 profile is a popular choice for enthusiasts looking for improved performance, offering a 282-degree duration. This means the valves stay open longer, allowing more air and fuel into the cylinder and more exhaust out. It's a direct replacement for your stock right exhaust cam, and while it's designed to work with your existing valvetrain, it's often paired with other performance modifications to really unlock its potential. Keep in mind that this part is not CARB approved and cannot be shipped to California.
