Pulstar Spark Plugs use innovative plasma-assisted combustion technology to increase horsepower and torque. Plasma-assisted combustion is already used to improve engine performance in race cars, but requires complex control systems and costs nearly $2,000 per cylinder. Pulstar Spark Plugs, manufactured by Enerpulse Technologies, brings plasma-assisted combustion to consumers with a simple spark plug upgrade. Pulstar uses a patented internal capacitor, developed with the help of a US DoE laboratory, to create a high-intensity electrical pulse that ionizes the air-fuel mixture and saturates it with combustion-enhancing plasma. With its plasma-assisted combustion, Pulstar ignites fuel instantly and burns it rapidly; gaining up to 7 horsepower, 9 ft.-lbs. of torque … and, delivering wicked throttle response.

Delphi OE technology ignition products are validated to match the vehicles system; OE quality replacement parts for the right fit , form and function; Delphi coils provide OE performance, durability and electromagnetic capacity level requirements.

Product Features:

Delphi coils provide OE performance, durability and electromagnetic capacity level requirements
Delphi ignition coils are designed to operate as part of an integral engine management system to insert power into spark plugs and ensure fast starts; consistent engine performance and optimized fuel efficiency
Delphi uses winding process techniques to control the length of wire between adjacent windings; that’s important since more length means greater voltage differences and can create more pressure that could break down the insulation and wire coating
We back our ignition coil design with proven materials, such as high quality wires and wire coating that resists the cracks, pin holes and imperfections that most often lead to failure issues

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
