ACDelco GM Genuine Parts Ignition Coils
ACDelco GM Genuine Parts ignition coils are the true OE parts installed during production or validated by GM, for GM vehicles--designed, engineered, and tested to rigorous standards and backed by General Motors. They increase 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. GM Genuine Parts 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.

Professional Products LSX High Performance Coil Packs
Give some more spark to your ignition system using these Professional Products LSX high performance coil packs. They provide a maximum voltage of 40 kV and the longest spark duration available. The coil packs fire 1/8th as many times as the old single coil systems, providing eight times as long for the coil to regenerate power for the next spark. On multiple coil setups like these LSX high performance packs, longer spark duration is highly desirable to ensure that 100 percent of the intake charge is ignited—for maximum power throughout the entire rpm range.

Mishimoto Ignition Coils
The basic requirements for a properly running engine are fuel, air, compression, and spark. A weak spark from your ignition system can result in misfiring under high-load driving, and spark blow-out under high boost, which is bad for performance. Mishimoto ignition coils are high-quality replacements that can bring your vehicle up to Stage 0 before moving on to horsepower adding modifications. They are designed and tested to meet or exceed OEM performance standards and are available as a single coil or in sets. Once installed with a set of new spark plugs, you can expect a refreshed ignition system with improved engine startup, a smoother idle, and restored performance. The primary frame of Mishimoto coils is constructed from extremely robust phenolic resin, ensuring optimal longevity in high-temperature environments, while a precision lower rubber boot provides a barrier against moisture entry into the plug well, eliminating chances for spark plug contamination. Each coil is pre-lubricated with dielectric grease to prevent corrosion and ensure an optimal connection between the spark plug and coil. Swap out your worn or defective factory coils with Mishimoto's ignition coils, and as with all their products, the coils include their signature Mishimoto Lifetime Warranty. Choose the ones designed for your vehicle in the quantity needed.
