ACDelco Gold Automotive AGM Batteries
ACDelco Gold Automotive AGM batteries have high-cycling capabilities, are remarkably charge-receptive, and are necessary for start/stop applications. These batteries are also maintenance-free, 100 percent pressure-tested against leaks, and are manufactured to resist corrosion. Best of all, they are backed by ACDelco's outstanding warranty coverage. When reliable starting power is a priority— ACDelco Gold Automotive AGM batteries are the answer! Additional features include: * Absorbed Glass Mat design is 100 percent leak and spill-proof, because the electrolyte is permanently held in the glass mat separator, instead of free flowing within each cell * Oxygen recombination reduces water loss and reassures maintenance-free performance * ACDelco Gold Automotive AGM batteries have longer life expectancy in traditional vehicle applications, due to a maintained pressure on the plates, which significantly reduces the amount of active mass lost from the grid

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.

NGK Laser Iridium Spark Plugs
NGK Laser Iridium spark plugs feature laser-welded technology. Lasers are used to pinpoint precision welds, reducing excess debris; this decreases the required voltage to bridge the spark gap. An iridium disc is welded on the center electrode and a platinum disc is welded on the ground electrode, reducing the wear rate of both surfaces and ensuring great durability and long life. These spark plugs are available for use with a variety of engine types.
