9mm Performance Spark Plug Wires – 6.2L - Ceramic

GM LS Ceramic Ignition Wire Set

High-quality ignition wire set for GM Gen 4 LS engines such as LS3, LS4 and LS7. The wires are equipped with ceramic spark plug boots, providing significantly higher heat resistance compared to traditional rubber or silicone boots. This makes them especially suitable for engines with high temperatures around exhaust manifolds or headers.

The cables are constructed with a spiral core and thick silicone insulation, ensuring stable spark delivery, good current transfer and long service life. The spiral core also helps reduce electrical noise and protects the vehicle’s electronics from interference.

With high resistance to both EMI (electromagnetic interference) and RFI (radio frequency interference), the risk of electrical disturbances from or to other electronic components in the vehicle is minimized.

A good choice for performance, motorsport and street vehicles where reliable ignition cables with high heat resistance are required.
