Restore a clean high-voltage path between the ignition coil and spark plug with the ThunderCore PRO Coil Boot 900-P2044. In coil-on-plug (COP) and coil-near-plug (CNP) systems, the coil boot forms the insulative connection between the coil and the plug, and heat, vibration, or chemical exposure can break it down over time. It installs as a direct-fit replacement for the 2002-2005 Ford Thunderbird, 1999-2004 Jaguar S-Type, 2004 Jaguar XJ8, and 2000-2006 Lincoln LS — see the Buyer's Guide tab for engine-level fitment.
Arc-through, misfires, or hard starting can be signs that a coil boot has degraded. If a failed boot is the cause, this OE-replacement piece is designed to restore proper high-voltage insulation and a secure coil-to-plug contact.
