Return PolicyThe 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 low resistance spark plug wire there is only 40 - 50 ohms of resistance! That is the lowest resistance of any helically wound wire.
To accomplish this, 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. 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.

Too short msd spark plug wires - what do I do? I have a 34 ford running a 350 Chevy. I am using a msd pro- billet HEI distributor with msd 8.5 mm HEI wires. The problem is that the wires are not long enough to run through a loom from plugs to distributor. Any suggestions? I purchased both from you. Thanks for the help
