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:

Bolt-on Performance
Custom Fit For Make And Model Listed
Wires Are Pre-Cut To Exact Specifications
Conductor core features DuPont Kevlar material for increased tensile strength
Durable outer sleeve is a proprietary compound for resistance to high heat or abrasion
Stainless steel terminals feature dual crimp tabs to grip wire conductor and outer jacket separately

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
