What's in the Box
Wires feature straight boots with 90 degree boots on the ignition end.
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 of low resistance wire there is only 40-50 ohms of resistance! That is the lowest resistance of any helically wound wire.
MSD uses a copper alloy conductor due to its 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. There is over 40 ft of conductor wrapped into a 1 ft of plug wire. This winding procedure, with a ferro-magnetic impregnated center core, produces an extremely effective Electro Magnetic Interference (EMI) "choke". This suppression capability keeps the EMI inside the wire where it cannot interfere with other electronics. The sleeve surrounding 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.
