Keep high-voltage spark flowing cleanly from the ignition coil to the plug with the ThunderCore PRO Coil Boot 900-P2113, an OE-replacement boot that drops in on the 1997-2001 Infiniti Q45. In coil-on-plug (COP) and coil-near-plug (CNP) setups, the coil boot is the insulative path between the ignition coil and the spark plug; over time heat, vibration, and chemical exposure can degrade it, which may lead to arc-through, misfires, or hard starting.
Designed for compatibility with factory ignition coils and spark plugs in COP and CNP configurations. See the Buyer's Guide tab for the full engine-level fitment.
