ThunderCore PRO Coil Boot P/N:900-P2049
Keep spark energy where it belongs with the ThunderCore PRO ThunderSpark Coil Boot Kit 900-P2049-8, an OE-replacement kit that helps restore spark isolation and secure coil-to-plug contact. It installs as a direct-fit replacement for the 2004-2006 Nissan Titan — see the Buyer's Guide tab for engine-level coverage.
In coil-on-plug (COP) and coil-near-plug (CNP) systems, the coil boot is the insulative path between the ignition coil and the spark plug. Heat, vibration, and chemical exposure can degrade these boots over time, leading to arc-through, misfires, or hard starting. If worn or cracked boots are the cause, this kit replaces them.
What does this coil boot kit do?
It provides the insulative path between the ignition coil and the spark plug in coil-on-plug and coil-near-plug systems, helping maintain high-voltage insulation and secure coil-to-plug contact.
