Product Details

This is the COMP Cams XFI AFM 220/232 Hydraulic Roller Camshaft, designed for GM LS GEN IV engines. It's a well-built camshaft that offers a great all-around performance upgrade, especially for those looking to get more out of their engine without sacrificing the factory Active Fuel Management (AFM) system. If you're working on a mildly modified L99 Camaro or similar LS-based engine that retains AFM, this camshaft is a popular choice.

The camshaft features a 220 intake and 232 exhaust duration at .050 lift, with a 113-degree lobe separation angle.

You can expect improved throttle response and a noticeable increase in power across the RPM range. It's a solid option for street-driven vehicles that see daily use but also get taken out for spirited drives.

When installing this camshaft, it's important to ensure you have the correct supporting components. This includes checking your valve springs, pushrods, and timing set to make sure they are compatible with the camshaft's specifications. Refer to the manufacturer's installation instructions for detailed guidance on proper setup and break-in procedures to ensure optimal performance and longevity.
