GSC P-D Hyundai Genesis Coupe 2.0L Turbo (G4KF) S3 Cams 280/280 Billet (Upgraded Springs Required)

If you're looking to get more out of your Hyundai Genesis Coupe's 2.0L Turbo G4KF engine, a camshaft upgrade is a solid way to change its breathing characteristics. These GSC Power Division S3 camshafts are designed to improve airflow into and out of your engine, which can lead to noticeable gains in power and torque, especially when paired with other supporting modifications. They feature a 280-degree duration on both the intake and exhaust sides, meaning the valves will stay open longer, allowing more air and fuel mixture in and more exhaust gases out.

These S3 cams are ground from a solid billet core, which is a strong and durable material that allows for more aggressive profiles than a stock cam. The 280/280 profile is a popular choice for builds aiming for a significant increase in performance, often seen in track-focused or heavily modified street cars. Because these cams require the valves to open and close more aggressively and at higher speeds, it's essential to use upgraded valve springs. The stock springs won't be able to keep up, and you risk valve float or even piston-to-valve contact. GSC Power Division is well-known in the performance tuning community for their well-built engine components.

When installing these camshafts, remember that you'll need to ensure your engine's valvetrain can handle the increased lift and duration. This means upgrading your valve springs is a must, and you should also check your valve timing to ensure it's set correctly for optimal performance and engine safety. Because these are not CARB approved, they cannot be shipped to California.
