ThunderCore PRO Coil Boot P/N:900-P2039
Keep high-voltage current traveling cleanly from the ignition coil to the spark plug with the ThunderCore PRO Coil Boot 900-P2030. In coil-on-plug (COP) and coil-near-plug (CNP) ignition systems, the coil boot forms the insulative path between the coil and the plug; heat, vibration, and chemical exposure can degrade it over time, which may lead to arc-through, misfires, or hard starting. This OE-replacement boot fits the 2005-2006 Ford GT; 1999, 2001, 2003-2004, and 2007-2014 Ford Mustang; 2003-2005 Lincoln Aviator; 2002 Lincoln Blackwood; 1999-2002 Lincoln Continental; 1997-1998 Lincoln Mark VIII; 1999-2004 Lincoln Navigator; and 2003-2004 Mercury Marauder — see the Buyer's Guide tab for engine-level fitment.
If a degraded coil boot is the cause of your misfire or hard-start condition, this replaces it. Diagnose the underlying cause before servicing.
