Our Spark Plug wire kits for LS engines are American made. These 10mm spiral-core wires feature high-temperature silicone insulation. Eliminate ignition noise, voltage leaks, and a loss of power when switching to Scott Performance spark plug wires.

The spark plug wires’ high-temp silicone and fiberglass blend sleeves are resistant to high temperatures, abrasions, and tears. Our sets feature angled boots at both ends, with a 45-degree coil boost and 45-degree plug boot. This ensures a tight, secure fit, without getting in the way.

Scott Performance Wire’s preparatory 30 Gold suppression core wires are a unique internal spiraling. Standard OEM wires typically have 10,000 to 12,000 ohms per foot of resistance, however, our 30 Gold wire kits feature 30 ohms per resistance per foot, producing a more robust and accurate spark. The kits also provide strong construction and reliability.

With over 45 years of experience, Scott Performance Wires has supplied wires to winners in NASCAR and NHRA teams. We pride ourselves on making the best wire for you, with everything being made right here at our facility in North Carolina.
