Alright, gearheads with GM LS motors (LS1, LS2, LS3, LS6, LS7, LSA, you name it), listen up. This Dragon Fire Performance spark plug wire set is built to deliver a strong, reliable spark without any fuss. They're a direct fit replacement, so they'll hook right up to your 1999-2019 Buick, Chevy, GMC, Cadillac, Pontiac, or Hummer with an LS-based V8. The wires are a beefy 8.5mm thick with a resistance of about 500 ohms per foot. Inside, there's a Kevlar-reinforced core and a low-resistance spiral-wound conductor designed to handle up to 80,000 volts – that means maximum spark energy gets to your plugs. The insulation is a high-grade silicone and EPDM blend that stands up to heat (rated to 600°F), oil, and abrasion, and it does a great job suppressing radio frequency interference (RFI/EMI). The boots are extra thick silicone too, for a tight, weatherproof seal at the plug and coil. Each wire is about 10.5 inches long. If you're doing a tune-up, chasing better performance, or just need reliable OEM-style replacements, these wires are a solid choice from a solid brand. Just double-check the fitment for your specific model and year before you click buy.
