Workhorse W21 Ignition Coils and Boots

Carquest Premium ignition coils meet or exceed original equipment (OE) specifications and are developed by top OE/OES manufacturers to ensure superior performance. All of our Carquest Premium ignition coils are developed by IATF 16949 certified manufacturers for consistent durability and long-lasting performance. These ignition coils use high-quality components and will utilize optimized designs on applications where the OE ignition coil had frequent failures. We require stringent testing standards to ensure proper fit and performance for each application and stand behind our Carquest Premium ignition coils with an industry-leading warranty. Carquest Premium ignition coils are part of our Carquest Vehicle Solutions, which is a full line of engine management and electronics products that help control ignition, fuel delivery and emission systems. Carquest Vehicle Solutions are OE-quality parts designed, engineered and tested by world-class manufacturers to ensure a reliable and long-lasting repair.

Product Features:

• Computer-Aided Design (CAD), laser scanning and 3D printing – utilizing Fused Deposition Modeling (FDM) and Stereolithography (SLA) – in the part design process ensures speed-to-market and a precise fit guaranteed.
• 100% pure copper precision-wound windings increase coil life and ensure reliability and maximum coil output when needed.
• Highly conductive aluminum alloy secondary terminal guarantees secondary coil terminals will not oxidize (rust), will provide excellent conductivity, extended coil life and will not cause excessive stress on the primary control circuit.
• 100% thermo-shock and vibration tested to ensure superior performance in extreme conditions.
• 100% end-of-line tested to ensure confidence and product reliability, every time.

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 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 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.

Product Features:

• High quality coated windings to improve durability and provide protection against internal shorts and dielectric breakdown
• Silicone steel plates surrounding the ignition coil correctly match the original part size and number exactly
• Laminations are coated to hinder corrosion and many feature molded plastic protection to help ensure that nothing is exposed
• GM-recommended replacement part for your GM vehicle’s original factory component
• Offering the quality, reliability, and durability of GM OE
• Manufactured to GM OE specification for fit, form, and function
