Seal high-voltage spark where it belongs and keep your coil-on-plug ignition firing clean with the ThunderCore PRO Coil Boot 900-P2018 (also written 900P2018). This ThunderSpark OE-replacement coil boot is a direct-fit part for the 2001 Hyundai XG300, 2002-2005 Hyundai XG350, 2002-2005 Kia Sedona, 2003-2006 Hyundai Santa Fe, 2003-2006 Kia Sorento, and 2004-2006 Kia Amanti — see the Buyer's Guide tab for engine-level detail.
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. Over time boots degrade from heat, vibration, and chemical exposure, which can lead to arc-through, misfires, or hard starting; if a worn or cracked boot is the cause, this part 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-temperature silicone and reinforced materials to resist oil, fuel, and under-hood heat.
