MSD Ignition – MSD Ignition Super Conductor Spark Plug Wire Set – 99-13 Gm Truck & Suv – Red, 32829 (Part No.32829)

MSD Ignition Super Conductor Spark Plug Wire Set - 99-13 Gm Truck & Suv - Red, 32829

from

$124.99
“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 11-inch length of super conductor wire, there are 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 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 are over 40 feet of conductor wrapped into a single foot of plug wire. This winding procedure, combined with a ferromagnetic 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 produces a sleeve that is highly resistant to high heat as well as abrasion and tears. The MSD’s 8.5mm spark plug terminals feature dual drimp terminals. As the name implies, the terminals feature two crimps: one for the sleeve of the wire and another separate crimp to grasp the conductor.”
