GM LS Ceramic Ignition Cable Set

GM LS Ceramic Spark Plug Wire Set – 135° Boot, 275 mm

Built for LS engines where the plug wires sit right next to the headers. The ceramic spark plug boots withstand far more heat than standard silicone boots, so they won't melt, burn through or cause misfires with aftermarket headers, turbo manifolds and in tight engine bays.

The 9 mm silicone wire with a spiral-wound core resists high temperatures and keeps EMI/RFI interference low. That protects your ECU, sensors and data logging from ignition noise.

Why ceramic boots?
Aftermarket headers and turbo manifolds often sit only millimetres from the plugs. Ceramic boots handle that heat, so you don't need separate boot sleeves.

Install tip: ceramic is brittle. Remove the boot by twisting it by hand, don't pull on the wire, and route the wires away from the headers.
