Keep high-voltage spark energy where it belongs with the ThunderCore PRO Coil Boot Kit (P/N 900-P2048-4), an OE-replacement kit that restores the insulative path between the ignition coil and the spark plug in coil-on-plug (COP) and coil-near-plug (CNP) systems. It installs as a direct-fit service kit for the 2002-2009 Nissan Altima, 2009 Nissan Cube, 2005-2010 Nissan Frontier, 2009-2010 Nissan Rogue, 2002-2008 Nissan Sentra, 2009-2010 Nissan Versa, and 2002-2006 Nissan X-Trail — see the Buyer's Guide tab for engine specifics.
- Exact OE Fit: designed for compatibility with factory ignition coils and spark plugs in coil-on-plug and coil-near-plug setups.
- Heat & Chemical Resistant: built from high-temp silicone and reinforced materials to resist oil, fuel, and under-hood heat.
- Restores Ignition Insulation: replaces worn or cracked boots to help maintain proper spark isolation.
- Complete Kit Coverage: includes the boots, springs, and insulators needed for full-cylinder service.
Over time, coil boots can degrade from heat, vibration, or chemical exposure, which may lead to arc-through, misfires, or hard starting. If worn coil boots are the cause, this kit replaces them for a full ignition tune-up or preventative maintenance.
