Product Details
These Granatelli coil-near-plug wire connector kits are built with high-temperature yellow silicone jacketing and a black fire sleeve. This combination is designed to handle the heat generated by powerful LS engines, helping to ensure a consistent spark delivery. They are a solid option for anyone working on GM vehicles from 1999 through 2023 that use LS2, LS3, LSA, LS7, or LS9 engines.
The yellow silicone jacketing offers good dielectric properties and resistance to heat, while the black fire sleeve adds an extra layer of protection against radiant heat and abrasion. This dual-layer approach is common in performance applications where engine bay temperatures can get quite high. These kits are designed to fit right onto the coil and spark plug, making them a straightforward replacement or upgrade for many GM cars and trucks, including models like the Cadillac CTS, Chevrolet Camaro, and Pontiac GTO.
When you're rebuilding the ignition system on a performance GM vehicle, ensuring your spark plug wires can withstand the engine's operating conditions is key. These Granatelli connectors offer a well-built solution to help maintain reliable ignition performance.
