Restore reliable spark insulation with the ThunderCore PRO Coil Boot 900-P2042. In coil-on-plug (COP) and coil-near-plug (CNP) ignition systems, the coil boot forms the insulative path between the ignition coil and the spark plug, carrying high voltage to the plug while sealing out under-hood heat and moisture. It drops in as an OE-replacement boot for a wide range of Ford, Mazda, and Mercury applications — including the 2001-2006 and 2008 Ford Escape, 2005-2007 Ford Five Hundred, 2005-2007 Ford Freestyle, 2000 and 2004-2005 Ford Taurus, 2003-2008 Mazda 6, 2001-2006 and 2008-2009 Mazda Tribute, 2005-2007 Mercury Montego, and 2000-2005 Mercury Sable. See the "Vehicles it fits" section for the full list.
- Restores Ignition Insulation: Replaces a worn or cracked boot to maintain proper spark isolation and help prevent voltage loss.
- OE Replacement Quality: Engineered to match OE dielectric strength, boot length, and connector geometry for coil-to-plug contact.
- Heat & Chemical Resistant: Constructed from high-temperature silicone and reinforced materials to resist oil, fuel, and engine-bay heat.
Over time boots can degrade from heat, vibration, or chemical exposure, which can lead to arc-through, misfires, or hard starting. If a failed boot is the cause, this part replaces it.

Frequently Asked Questions
What does the coil boot do?
It forms the insulative path between the ignition coil and the spark plug in coil-on-plug and coil-near-plug systems, carrying high voltage to the plug while sealing out heat and moisture.
What are signs a coil boot may need replacing?
Boots can degrade from heat, vibration, or chemical exposure, which may cause arc-through, misfires, or hard starting. Diagnose the cause before replacing.
What is this coil boot made of?
It is constructed from high-temperature silicone and reinforced materials designed to resist oil, fuel, and under-hood heat.
Will this fit my vehicle?
It fits a range of Ford, Mazda, and Mercury models, such as the 2001-2006 and 2008 Ford Escape and 2003-2008 Mazda 6. Check the "Vehicles it fits" section for the full list.
Is this an OE-replacement part?
Yes. It is an OE-replacement boot engineered to match OE dielectric strength, boot length, and connector geometry for consistent coil-to-plug contact.
