9042 SuperStock 8mm Extreme 9000 Series Black Custom Ferro-Spiral Core Spark Plug Wire Set

ACCEL Extreme 9000 Ferro-Spiral Spark Plug Wire Sets use space-age technology to create an ultra-high-temperature barrier that acts as a heat mirror, reflecting the infrared energy from the spark plug boot. Engineered for supercharged and turbocharged engines with exhaust manifolds that can reach 1,000 degrees and actually glow red-hot, they resist heat and help keep boots from melting or burning. Designed for 5.0L and 5.7L GM V8s, these black 8mm wire sets feature 600-degree-rated double-silicone construction, a heavy-gauge copper-nickel alloy conductor, 500 ohms per foot of resistance, a Ferro-Spiral core developed for high-performance street use, and stainless steel terminals. They deliver maximum spark energy to the plugs with the highest level of RFI/EMI suppression and come backed by a limited one-year warranty.
