What is the primary benefit of this camshaft for my LS engine?

This COMP Cams XFI RPM HI-LIFT camshaft is designed to improve performance in mildly modified GM LS GEN IV VVT engines. It offers a broader powerband and increased lift compared to stock, making it a popular choice for applications where the AFM system has been disabled.

Does this camshaft require any special installation considerations?

Yes, this camshaft is intended for use in applications where the Active Fuel Management (AFM) system has been disabled. This typically means you will need to replace the stock AFM lifters and trays with non-AFM components for proper operation and reliability.

What other parts might I need when installing this camshaft?

When upgrading to a performance camshaft like this one, it's recommended to also check the condition of your valve springs, pushrods, and timing set. Ensuring these supporting components are compatible and in good working order will help you achieve optimal performance and durability.

The XFI RPM HI-LIFT series is known for its well-built construction and carefully engineered profiles. This particular camshaft aims to provide a broad powerband, making it suitable for daily drivers that also see spirited use.
