1972 GMC Sprint 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.

Product Features:

• Silicone boots protect against high exhaust temps
• Kevlar core combination for great strength and durability
• Heavy duty terminals for secure connection
• 8mm silicone and synthetic jacket resists heat and abrasion
• 500 Ohms/ft. Resistance For Improved Spark Delivery And Power
• Silicone boots protect against high exhaust temps

This combination is encased in a heavy duty sleeve that will withstand abrasion and high temperatures. Cap off each end with our Dual Crimp Terminals and you have the best wire available.

Product Features:

• Less than 50 ohms per foot for superior spark
• Ferro-magnetic impregnated core creates an effective EMI choke
• Forty feet of conductor is wound into a single foot of wire for high EMI suppression
• Conductor core features Dupont Kevlar material for increased tensile strength
• Durable outer sleeve is a proprietary compound for resistance to high heat or abrasion
• Proprietary compound sleeves for resistance to high heat/abrasion

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 Super Conductor Wire there is 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 it’s 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. The MSD’s 8.5mm spark plug terminals feature Dual Crimp 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.
