This aftermarket component addresses the Active Fuel Management (AFM) system found in certain General Motors vehicles, specifically those equipped with V8 engines like the Pontiac G8. AFM, also known as Displacement on Demand (DOD), deactivates cylinders under light load conditions to improve fuel economy. The installation of this kit effectively disables the AFM system.
Eliminating the factory AFM system offers several potential advantages. Some owners report improved engine reliability and reduced oil consumption, issues sometimes associated with the long-term operation of the AFM components. Furthermore, performance enthusiasts may prefer consistent V8 operation, foregoing the fuel economy benefits in favor of a more responsive and predictable driving experience. This modification is often pursued when building higher-performance engines.
