ACDelco Professional Ignition Coils are a high quality alternative to Original Equipment (OE) parts. When your vehicle begins to suffer from engine misfires, rough idling, or hesitation during acceleration, a failing ignition component is often the culprit behind that stubborn check engine light. Acting as a transformer, these vital parts take standard battery voltage and convert it into the powerful electrical charge required to ignite the fuel mixture, working directly with the spark plugs to complete the combustion cycle. Restoring these critical links ensure reliable engine starts even in freezing climates and promotes smooth, consistent performance whether you are navigating daily stop-and-go traffic or taking long highway road trips. Engineered to handle demanding under-hood temperatures, coated windings improve durability and prevent internal shorts coated laminations hinder corrosion and protect components silicone steel plates surround the ignition coil. ACDelco 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.
