This {hardware} bundle successfully removes the Displacement on Demand (DOD) system from particular Basic Motors LS-based engines, primarily these present in Pontiac G8 GT automobiles. The DOD system, often known as Energetic Gas Administration (AFM), deactivates cylinders beneath gentle load situations to enhance gas economic system. The equipment usually consists of elements corresponding to a non-DOD camshaft, lifters, valley cowl, and gaskets needed for the conversion.
Eliminating the factory-installed system addresses considerations associated to potential mechanical failures related to the DOD lifters, which might result in important engine injury. Moreover, this modification permits for improved engine efficiency and elevated reliability, notably when aiming for greater horsepower ranges by aftermarket efficiency enhancements. The unique system, whereas supposed to enhance gas effectivity, is usually considered as a bottleneck to reaching optimum efficiency in these engines. This conversion ensures all cylinders are lively always, offering a extra constant energy supply.
