An ACDelco GM Original Equipment Ignition Coil is a GM-recommended replacement for your vehicle’s original component, and undergoes more stringent testing than aftermarket products. It increases electrical system voltage to help ignite the airfuel 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 Coil uses pure copper windings to improve durability and provide higher resistance to internal shorts and dielectric breakdown. Because the number and shape of the laminations determine the output characteristics of an ignition coil, ACDelco ensures that the silicone steel plates surrounding the coil correctly match the original part size and number. Since steel laminations work best when they are new, shiny, and clean, ACDelco laminations are coated to hinder corrosion and many feature molded plastic protection to help ensure that nothing is exposed. This original equipment ignition coil has been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors.

Every single Delphi ignition coil is designed and endurance tested using high quality materials. This ensures fast starts, consistent engine performance and optimized fuel efficiency. We makes more than 10 million ignition coils for North America each year, and each one is engineered to OE design specifications for vehicles from Ford, Toyota, Nissan, Lexus, GM, Mazda, Chrysler, Subaru, Acura and more.

Product Features:

Delphi coils provide OE performance, durability and electromagnetic capacity level requirements
Delphi ignition coils are designed to operate as part of an integral engine management system to insert power into spark plugs and ensure fast starts; consistent engine performance and optimized fuel efficiency
Delphi uses winding process techniques to control the length of wire between adjacent windings; that’s important since more length means greater voltage differences and can create more pressure that could break down the insulation and wire coating
