Product Attributes
| Terminal Quantity | 2 |
| Voltage | 12 2H |
| Features & Benefits - Bullet 6 | Manufactured to meet specifications for fit, form, and function for General Motors vehicles as well as most makes and models |
| Product Description | ACDelco Gold (Professional) Ignition Coils are a high quality alternative to Original Equipment (OE) parts. 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 Gold (Professional) Ignition Coils use 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. ACDelco Gold (Professional) parts are manufactured to meet your expectations for fit, form, and function, making them a smart choice for General Motors vehicles, as well as most makes and models, including special applications. These high-quality parts are backed by General Motors. Some ACDelco Gold parts may have formerly appeared as ACDelco Professional. ⚠<b> WARNING:</b> Cancer and Reproductive Harm - www.P65Warnings.ca.gov |
