GSC P-D 08-16 Mitsubishi Evo X 4B11T S3 Cams 280/280 Billet

GSC Power Division is well-known for making serious engine components for performance applications. If you're looking to get the most out of your 2008-2016 Mitsubishi Evolution X with the 4B11T engine, their S3 camshafts are a solid option. These aren't just mild upgrades; they're designed to significantly change how your engine breathes, especially when you're pushing it hard.

What sets these cams apart is their billet construction. This means they start from a solid piece of steel and are machined to precise specifications, making them incredibly strong and durable. This strength is crucial for handling the increased stress and higher RPMs that performance builds often see. The S3 profile features a 280-degree duration on both the intake and exhaust sides. This aggressive profile is chosen to maximize airflow and power output, particularly in the mid-to-upper RPM range, making it a popular choice for track cars or serious street performance builds where peak power is the goal. You'll want to ensure your valvetrain components, like valve springs and retainers, are up to the task of handling these cams; GSC often recommends their own upgraded valvetrain for optimal performance and reliability.

Keep in mind that these camshafts are not CARB approved and cannot be shipped to California. They are intended for off-road or competition use where emissions regulations may differ. If you're building a high-performance Evo X and want to unlock more power from your 4B11T, these GSC S3 cams are a well-made component that can help you reach your goals.
