Keep every cylinder firing clean with the ThunderCore PRO Coil Boot 900-P2036, an OE-replacement boot that restores the insulative path between the ignition coil and the spark plug. It drops in as a direct-fit replacement for the 2000-2001 Jeep Cherokee, 1999-2004 Jeep Grand Cherokee, 2000-2006 Jeep TJ, and 2000-2006 Jeep Wrangler — see the Buyer's Guide tab for engine specifics.
In coil-on-plug (COP) and coil-near-plug (CNP) systems, the coil boot carries high voltage from the coil to the plug while insulating it from surrounding metal. Over time boots can degrade from heat, vibration, or chemical exposure, which may lead to arc-through, misfires, or hard starting. If a worn or cracked boot is the cause, this replaces it to restore spark isolation.
- Heat & Chemical Resistant: made from premium silicone and reinforced high-temperature materials that resist oil, fuel, and under-hood heat.
- OE Replacement Quality: matched to OE dielectric strength, boot length, and connector geometry.
- Restores Ignition Insulation: replaces worn or cracked boots for proper spark isolation and to help prevent voltage loss.
- COP/CNP Fitment: designed to seat with factory ignition coils and spark plugs in coil-on-plug and coil-near-plug systems.
