An ACDelco Professional, premium aftermarket Ignition Coil is a high quality replacement for many vehicles on the road today. 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 Professional Ignition Coil uses pure copper windings to improve durability and provides 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 ignition 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 premium aftermarket replacement ignition coil is manufactured to meet your expectations for fit, form, and function.

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

The MSD 8.5mm super conductor wire is the performance wire. Engineered from the inside out, the 8.5 offers everything you have ever wanted in a wire; incredibly low resistance without electronic interference. In a single 12 inch length of super conductor wire there is only 40 – 50 ohms of resistance. That is the lowest resistance of any helically wound wire. To accomplish this, we use a copper alloy conductor due to it’s great voltage carrying capabilities. The low resistance results in less loss in spark energy so more reaches the spark plug. The conductor is wound extremely tight around a special center core. So tight in fact, that there is over 40 feet of conductor wrapped into a single foot of plug wire. This winding procedure, combined with a ferro-magnetic impregnated center core, produces an extremely effective electro magnetic interference (EMI) or choke. This choke, or suppression capability, keeps the EMI inside the wire where it cannot interfere with other electronics on your vehicle. The outer sleeve that surrounds the conductor assembly is just as impressive. A proprietary blend of silicone and synthetic material produce a sleeve that is highly resistant to high heat as well as abrasion and tears. Available in universal kits and bulk lengths.

Product Features:

• Less than 50 ohms per foot for superior spark
• Ferro-magnetic impregnated core creates an effective EMI choke
• 40 ft. Of Conductor Wound Into A Single Foot Of Wire
• For high EMI suppression
• Conductor core features Dupont Kevlar material
• Proprietary compound sleeves for resistance to high heat/abrasion
