Keep high-voltage spark traveling cleanly from coil to plug with the ThunderCore PRO Coil Boot 900-P2017, a direct-fit replacement for the 2001 Infiniti QX4 and 2001 Nissan Pathfinder — see the Buyer's Guide tab for engine-level fitment. 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 a boot over time, leading to arc-through, misfires, or hard starting; if a worn or cracked boot is the cause, this ThunderSpark boot replaces it.
Whether you're servicing a single cylinder or refreshing the ignition during a tune-up, this boot helps restore proper coil-to-plug contact and insulation on the listed applications.
