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.
GM LS (LS1, LS2, LS3, LS6, LS7, LSA) 1997-2013 cars; Gen V LT (LT1, LT4) 2014+ Corvette & Camaro
Fitment & options: Fits LS-powered cars (Corvette, Camaro, Firebird, GTO, CTS-V, Trailblazer SS, SSR, G8) 1997-2013 and 2014-and-up Gen V LT cars (C7 Corvette, sixth-gen Camaro). Running a 1999-2013 GM truck or SUV that needs a longer lead? See our GM Truck & SUV spark plug wires. Choose your boot angle (straight or 45 degree) and your Package (wires only, add heat boots in black, red, blue or yellow, or add a set of NGK TR55 plugs).
