ThunderCore PRO Coil Boot Kit P/N:900-P2071-4
Restore clean spark isolation and secure coil-to-plug contact with the ThunderCore PRO ThunderSpark Coil Boot Kit 900-P2071-6. It installs as a direct-fit replacement for the 2015 Chevrolet Colorado and 2015 GMC Canyon — see the "Vehicles it fits" section for engine-level coverage. In coil-on-plug (COP) and coil-near-plug (CNP) systems, the boot forms the insulative path between the ignition coil and the spark plug; heat, vibration, and chemical exposure can degrade it over time, which may lead to arc-through, misfires, or hard starting. If a worn or cracked boot is the cause, this kit replaces it.
By restoring proper high-voltage insulation, the kit helps return the ignition system to reliable, factory-level operation across the engine set.
