GSC P-D 08+ Subaru STi S1 Cams 266/264 Billet - Right Bank Intake

This is the GSC Power Division S1 camshaft for the right bank intake on 2008 and newer Subaru STi models. This camshaft is a direct replacement for your stock unit, designed to improve engine performance. The S1 grind features a 266-degree intake duration and a 264-degree exhaust duration, offering a noticeable bump in power, especially in the mid-range and upper RPMs, without sacrificing too much low-end torque. It's a popular choice for those looking to get more out of their EJ25 engine.

Crafted from a solid billet core, this camshaft is built for durability and consistent performance. The billet construction means it's machined from a single piece of high-strength steel, ensuring it can handle the increased stresses of performance driving. This updated grind is designed to work well with other modifications, making it a solid option for rebuilding or upgrading your STi's top end. Remember, this camshaft is not CARB approved and cannot be shipped to California.
