Restore reliable high-voltage insulation between your ignition coils and spark plugs with the ThunderCore PRO ThunderSpark Coil Boot Kit 900-P2029-8. In coil-on-plug (COP) and coil-near-plug (CNP) systems, the coil boot serves as the insulative path between the ignition coil and the spark plug, and over time boots can degrade from heat, vibration, or chemical exposure. This OE-replacement kit drops in across a wide range of Ford, Lincoln, and Mercury applications, including the 1998-2011 Ford Crown Victoria, 1997-2008 Ford F-150, 2003-2014 Ford E-150, 1999-2002 Ford Mustang, 2006-2011 Lincoln Town Car, and 1998-2011 Mercury Grand Marquis — see the Buyer's Guide tab for the full list of 74 applications.
- Restores Ignition Insulation: Replaces worn or cracked boots to help maintain proper spark isolation and reduce voltage loss.
- Complete Kit Coverage: Includes the boots, springs, and insulators needed for full-cylinder replacement — ideal for tune-ups and repairs.
- Heat & Chemical Resistant: Built from high-temp silicone and reinforced materials to resist oil, fuel, and under-hood heat.
- OE Replacement Quality: Engineered to match OE dielectric strength, boot length, and connector geometry for coil-on-plug and coil-near-plug systems.
If degraded coil boots are the cause of arc-through, misfires, or hard starting, this kit replaces them to help restore ignition reliability.
