A coil boot is the flexible insulator that seats over the spark plug and carries spark energy from the coil down into the plug well.
Over time boots can harden, crack, or arc. If a failed boot is the cause of a misfire, rough running, or a stored misfire code, this kit replaces the worn part. Diagnose the cause before replacing, since misfires can also stem from the coils, plugs, or other components.
