SPWEX8100 - UltraPower 8.1L Extreme Magnum Spark Plug Wires

These are the mack-daddy of all spark plug wires! Never burn another wire again!

UltraPower Extreme Magnum Spark Plug Wires are patent protected because of the unique method of producing these wires which have extremely low resistance while maintaining very high noise suppression. The benefit of this invention is that full electrical energy from the ignition source is transmitted to the spark plug. The end result of the application of this method is increased horsepower, torque, fuel economy and a smoother running engine. The heat resistant socks take the place of the metal heat shields used on the factory spark plug wires.

Features:

• Patented Solid Stainless Steel Core Spark Plug Wires with RF Eliminator
• The technology in these wires come straight from Nascar and is not available on the open market. They are made out of a patented zero OHM, solid core stainless steel wire wrapped by silver plated copper conductor wire and are outfitted with an RFI eliminator collar that guarantees no interference with radios.
• Wires are sleeved from top to bottom with high temperature fiberglass/acrylic socks that will withstand up to 1500º F & 1000º F continuously.
• Eliminates the need for the metal boot shield.
• These wires were engine dyno tested for 2500 hours under wide open throttle conditions and were the only wires that could hold up to those conditions. Even ceramic wires wouldn't last.
• Increase power to the spark plug up to 400% over stock!
• Adds up to 15HP on Big Block GM engines.
• True Life-Time Lasting Wires, Life-Time Warranty!

Applications:

• Workhorse chassis with 8.1L (2001-2011)
• Workhorse chassis with 6.0L (2004-2006)
• All GM vehicles with 8.1L (Silverado, Sierra, Avalanche, Yukon XL)
• Industrial applications with 8.1L (Generators, Forklifts, Pumps, Compressors, etc)
