Hinson Motorsports 8.5mm performance spark plug wires for 1999-2013 GM trucks and SUVs. The extended (~10.5 inch) leads route cleanly from the coil packs to the plugs on 4.8L, 5.3L, 6.0L and 6.2L LS truck engines. Built in the USA around a low-resistance copper-alloy spiral-wound core (~40-50 ohms/ft, 500 ohm/ft class) with a ferro-magnetic EMI suppression core that keeps electrical noise off your sensors and ECU.
Why builders choose these wires
- Maximum spark energy — low-resistance spiral core delivers more voltage to the plug for stronger, cleaner combustion.
- EMI/RFI suppression — ferro-magnetic core contains electrical noise so it can't interfere with engine electronics.
- Extended truck lead — longer ~10.5 inch routing made for coil-near-plug GM truck and SUV layouts.
- Built to survive heat — high-temperature silicone sleeve resists abrasion, tears and exhaust heat soak.
- Locked-on connections — dual-crimp terminals grip the conductor and the sleeve so boots stay put.
- Two boot angles — straight or 45 degree plug boots for the best clearance in tight engine bays.
