Keep high-voltage current traveling cleanly from the ignition coil to the spark plug with the ThunderCore PRO ThunderSpark Coil Boot 900-P2046. In coil-on-plug (COP) and coil-near-plug (CNP) systems, the coil boot serves as the insulative path between the coil and the plug, and this one drops in as an OE-replacement for the 2001-2006 Hyundai Santa Fe, 1999-2005 Hyundai Sonata, 2001-2006 Kia Magentis, and 2001-2006 Kia Optima — see the Buyer's Guide tab for engine-level fitment.
Over time, coil boots degrade from heat, vibration, and chemical exposure, which can lead to arc-through, misfires, or hard starting. If a failed coil boot is the cause of those symptoms, replacing it helps restore reliable high-voltage insulation and secure coil-to-plug contact. Diagnose the underlying cause before replacing.
