The COMP Cams Xtreme Energy 216/218 hydraulic roller camshaft kit for GM Ecotec engines is aimed at street/strip installations where stronger mid and top-end power is wanted. It improves responsiveness and torque across a broader RPM range. Installation assumes updated engine management; a programmer or computer modifications are required to fully tune the cam’s altered timing and deliver expected performance.
