9mm Performance Spark Plug Wires – 6.2L

GM LS Ignition Wire Set 135°

Ignition wire set for GM LS engines with a 135° spark plug boot, designed to provide better clearance around cylinder heads and exhaust manifolds. The cable features a spiral core with thick silicone insulation, ensuring stable spark delivery, high heat resistance, and effective protection against electrical interference.

The low resistance of approximately 300 ohms per 30 cm ensures strong current flow to the spark plugs and stable ignition even under high load. At the same time, the spiral core design helps reduce both EMI (electromagnetic interference) and RFI (radio frequency interference), preventing disturbances to other electronic components in the vehicle.

The wires are manufactured from heat-resistant silicone and are suitable for both performance engines and regular applications where reliable ignition cables with excellent insulation and long service life are required.
