An ACDelco GM Original Equipment Ignition Control Module is a GM-recommended replacement for your vehicle's original component, and undergoes more stringent testing than aftermarket products. It increases voltage in order for the spark plugs to ignite the air/fuel mixture as the starting and charging system starts the engine, maintains the battery's charge, and provides power to the electrical accessories while the engine is running. An ACDelco GM OE Ignition Control Module features electronically welded lead connections to help reduce heat stress, failure, or cold joints. It has been laser trimmed to provide precise values and reduce deterioration and damage. This ignition control module includes a copper slug heat sink to help dissipate heat and create a more stable environment and it also features a large bus bar for added support and conductivity to address the installation and operating forces that stress terminal tabs. This original equipment ignition control module has been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors.
