Red 8.5mm Spark Plug Wires – LS1-LS7, LSA & Gen V LT, Straight or 45° Boot

Upgrade your ignition with Hinson Motorsports 8.5mm performance spark plug wires, engineered for GM LS and Gen V LT V8s. Built in the USA around a low-resistance copper-alloy spiral-wound core, these wires push maximum spark energy to the plug while a ferro-magnetic core suppresses the EMI/RFI that can disrupt sensitive engine electronics. At roughly 40-50 ohms per foot, they run in the same 500 ohm/ft class as premium wires like MSD Super Conductor — at a builder-friendly price.

Why builders choose these wires

• Maximum spark energy — low-resistance spiral core delivers more voltage to the plug for cleaner, more complete combustion.
• EMI/RFI suppression — ferro-magnetic core keeps electrical noise inside the wire, protecting your ECU, sensors and data signals.
• Built to survive heat — high-temperature silicone sleeve resists abrasion, tears and header heat soak.
• Locked-on connections — dual-crimp terminals grip both the conductor and the sleeve so boots don't pull off.
• Two boot angles — choose straight or 45 degree plug boots for the best clearance around headers and accessories.
• Build it your way — add color-matched heat boots or a set of NGK TR55 spark plugs in the Package option.
