GSC P-D 08-16 Mitsubishi Evo X 4B11T S2 Cams 274/274 Billet

This is a set of GSC Power Division S2 camshafts specifically for the 2006, 2009-2015 Mitsubishi Lancer with the 4B11T engine. These camshafts are a key component in controlling your engine's breathing, dictating when the intake and exhaust valves open and close. Upgrading to these S2 cams can significantly change how your engine performs, especially if you're looking to get more power out of your 4B11T, whether for track use or spirited street driving.

These S2 cams are made from billet material, which is a solid piece of metal that's machined to shape. This construction method results in a very strong and durable camshaft that can handle higher stresses than cast cams. The 274 degrees of duration on both the intake and exhaust sides are designed to allow more air and fuel into the cylinders and more exhaust out, which is crucial for making more power. This specific grind is a popular choice for tuners looking for a noticeable improvement in the engine's powerband without going to an extreme setup.

When installing these camshafts, it's important to follow the manufacturer's recommended procedures. You'll want to ensure your valvetrain is in good condition, and it's often a good idea to replace valve springs and retainers when upgrading to more aggressive camshafts like these. Keep in mind that these camshafts are not CARB approved and cannot be shipped to California. Always refer to the GSC Power Division installation guide for the most accurate information regarding fitment and installation.
