    We started with black, 7mm suppressive core wire that will go through your looms. The 90° black plug boots are installed but you have to install the straight or 90° distributor ends. We even put in enough wire to place your coil on the firewall. Comes with straight boots for the distributor end of the plug wire. Black only.

    Two sets of boots/terminals are included, one set for conventional socket-type caps and one set for HEI type caps. The set includes 9 cables, the longest being 51" and the shortest being 24". Use eight for the plugs, one for the coil.

                The MSD 8.5mm Super Conductor Wire is "the" performance wire.Engineered from the inside out, the 8.5 offers everything you have everwanted 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) "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. The MSD 8.5mm Super Conductor Plug Wire is available in Universal Kits and Bulk Lengths.
