The high-temperature blue silicone jacketing is designed to withstand demanding engine bay conditions. Specific temperature ratings are determined by the manufacturer's internal testing for this application.

Does this kit include spark plug wires, or just the connectors?

This is a connector kit, meaning it includes the coil-near-plug connectors and protective sleeves. It is designed to work with your existing or new spark plug wires.

Product Details

These Granatelli Hi-Perf Coil-Near-Plug Wire Connector Kits are built with high-temperature blue silicone jacketing and a black fire sleeve, designed to handle the heat under the hood of many GM LS-based trucks and SUVs. If you're working on the ignition system for your L83 5.3L or L86 6.2L engine, this kit offers a solid option for replacing worn-out connectors.

The silicone jacket is rated for high temperatures, helping to ensure reliable spark delivery even in demanding conditions.

This kit is a direct replacement for the factory connectors, making installation straightforward for many 2014 model year GM vehicles like the Chevrolet Tahoe and GMC Yukon.
