Seal high-voltage spark and keep the ignition firing cleanly with the ThunderCore PRO Coil Boot 900-P2045. 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 — and this OE-replacement boot fits a wide range of Ford and Lincoln applications, including the 2004-2007 Ford F-150, 2005-2007 Ford Expedition, 2005-2007 Ford Mustang, 2006-2008 Lincoln Mark LT and 2006-2008 Mercury Mountaineer. See the Buyer's Guide tab for the full list.
- Restores ignition insulation: replaces worn or cracked boots to help keep proper spark isolation and prevent voltage loss.
- Heat & chemical resistant: constructed from high-temp silicone and reinforced materials designed to resist oil, fuel, and under-hood heat.
- OE-replacement fit: engineered to match OE dielectric strength, boot length, and connector geometry.
- COP/CNP compatible: designed for compatibility with factory ignition coils and spark plugs.
Over time, coil boots can degrade from heat, vibration, or chemical exposure, which can lead to arc-through, misfires, or hard starting. If a cracked or failed coil boot is the cause of those symptoms, this boot replaces it and helps restore secure coil-to-plug contact and high-voltage insulation.
