2003 GMC Sierra 1500 Performance Spark Plug Wires

The Street Fire Spark Plug Wires feature a low resistance conductor that’s wrapped in a sleek and durable black sleeve. The terminals are covered in black boots that protect the conductor from engine heat to ensure spark delivery.

When it comes to plug wires, resistance is king. The Street Fire Spark Plug Wires feature a low resistance (500 ohms per foot) conductor that’s wrapped in a sleek and durable black 8mm sleeve. A helical wound Kevlar-core combination provides an EMI-Noice resistant path from coil-to-plug. The heavy-duty terminals are wrapped in black silicone boots that protect the conductor from engine heat to ensure spark delivery. Light the fire, not your wallet-with MSD Street Fire.

“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.”
