An ACDelco Professional, premium aftermarket Ignition Coil is a high quality replacement for many vehicles on the road today. It increases electrical system voltage to help 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 Professional Ignition Coil uses pure copper windings to improve durability and provides 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 ignition 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 premium aftermarket replacement ignition coil is manufactured to meet your expectations for fit, form, and function.

Product Features:

• High quality coated windings to improve durability and provide protection against internal shorts and dielectric breakdown
