ThunderCore PRO Coil Boot P/N:900-P2098
Keep every cylinder firing cleanly with the ThunderCore PRO (ThunderSpark) Coil Boot Kit 900-P2098-6, an OE-replacement kit that restores the insulative path between the ignition coil and the spark plug. It's a direct-fit replacement for the 2007-2008 and 2010-2013 Nissan Altima and the 2009-2012 Suzuki Equator — see the Buyer's Guide tab for engine-level details on your application.
In coil-on-plug (COP) and coil-near-plug (CNP) systems, the coil boot provides the high-voltage insulation and secure coil-to-plug contact. Over time, heat, vibration, and chemical exposure can degrade the boot, leading to arc-through, misfires, or hard starting. If a worn or cracked boot is the cause, this kit replaces it.
Designed for factory ignition coils and spark plugs on the listed COP/CNP applications.
