The MSD 8.5mm Super Conductor Spark Plug Wire is the ultimate performance wire offering incredibly
low resistance without electronic interference. With less than 50 ohms of resistance,
the lowest resistance of any helically wound wire results in less loss in spark
energy so more reaches the spark plug. The conductor is wound extremely tight around
a special centre 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 centre 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. A proprietary blend of silicone
and synthetic material produce an outer sleeve that is highly resistant to high heat as
well as abrasion and tears.
