Description

Restore high-voltage spark insulation with the ThunderCore PRO Coil Boot Kit 900-P2045-8 (also written 900P20458), an OE-replacement kit for coil-on-plug (COP) and coil-near-plug (CNP) ignition systems. It fits a range of 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 vehicle and engine list. The coil boot serves as the insulative path between the ignition coil and the spark plug; over time boots can degrade from heat, vibration, or chemical exposure, leading to arc-through, misfires, or hard starting. If a worn or cracked boot is the cause, this kit replaces it.

OE Replacement Quality: engineered to match OE dielectric strength, boot length, and connector geometry.
Restores Ignition Insulation: replaces worn or cracked boots to help maintain proper spark isolation and reduce voltage loss.
Heat & Chemical Resistant: constructed from high-temp silicone and reinforced materials to resist oil, fuel, and under-hood heat.
Complete Kit Coverage: includes the boots, springs, and insulators needed for full-cylinder service — ideal for tune-ups and preventative maintenance.
