An AFM (Active Fuel Management) delete kit is a modification kit that is used to disable the AFM system in a vehicle's engine. The AFM system is designed to improve fuel economy by deactivating cylinders when they are not needed, such as cruising at a steady speed. However, this system can eventually lead to problems in some engines, such as excessive oil consumption and premature wear on engine components. An AFM delete kit includes components such as a new camshaft, lifter trays, and head bolts that are designed to replace the original components in the engine and eliminate the AFM system. By disabling the AFM system, the engine can operate more smoothly and with less wear, which can improve its overall reliability and performance.
