Restore high-voltage spark insulation and a secure coil-to-plug connection with the ThunderCore PRO Coil Boot 900-P2148. It installs as a direct-fit, OE-replacement boot for the 2014 and 2016-2018 Ford Fiesta — see the Buyer's Guide tab for the full engine coverage.
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. Heat, vibration, and chemical exposure can degrade the boot over time, which may lead to arc-through, misfires, or hard starting — signs this part may need replacing.
Designed for compatibility with the factory ignition coils and spark plugs on coil-on-plug and coil-near-plug systems.
