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

This is the GSC Power Division S3 Left Exhaust Camshaft, specifically made for the 2006-2007 Subaru 2.5L WRX and the 2004-2007 Subaru STi. If you're looking to get more performance out of your Subaru's engine, a camshaft upgrade like this can make a notable difference in how your engine breathes and performs at higher RPMs.

This camshaft is a billet piece, meaning it's machined from a solid block of steel for improved strength and durability compared to cast cams. The S3 profile is designed for a more aggressive ramp rate and increased lift, which helps the engine take in more air and expel exhaust gases more efficiently, especially when you're pushing the engine hard. It's important to note that this listing is for the left exhaust cam only, so you'll need to ensure you get the correct cam for your specific needs or purchase the full set if you're rebuilding the entire valvetrain.

Because this part is not CARB approved, it cannot be shipped to California. Always consult with a qualified mechanic or refer to GSC Power Division's installation guidelines for proper fitment and any other components you might need to complete your build, such as valve springs or retainers, to match the camshaft's performance characteristics.
