Keep high-voltage spark energy on its intended path with the ThunderCore PRO Coil Boot 900-P2049. In coil-on-plug (COP) and coil-near-plug (CNP) systems, the coil boot is the insulative link between the ignition coil and the spark plug — over time it can degrade from heat, vibration, or chemical exposure, leading to arc-through, misfires, or hard starting. This OE Replacement boot is a direct-fit replacement for a wide range of Infiniti and Nissan applications, including the 2003-2008 Infiniti FX35, 2003-2007 G35, 2002-2004 I35, 2006-2008 M35, 2001-2003 QX4, 2003-2006 Nissan 350Z, 2002-2006 Altima, 2005-2014 Frontier, 2002-2008 Maxima, 2003-2008 Murano, 2012-2013 NV1500/NV2500/NV3500, 2002-2012 Pathfinder, 2004-2009 Quest, 2004-2005 Titan, and 2005-2012 Xterra — see the Buyer's Guide tab for the full list.
- Heat & chemical resistant: built from high-temp silicone and reinforced materials to resist oil, fuel, and under-hood heat.
- Restores spark isolation: replaces worn or cracked boots to help maintain proper insulation and reduce voltage loss.
- OE Replacement quality: engineered to match OE dielectric strength, boot length, and connector geometry.
- Designed to fit factory ignition: made for coil-on-plug and coil-near-plug systems using the factory coils and spark plugs.
If worn or cracked coil boots are the cause of your misfires or hard starts, this boot replaces them to restore proper high-voltage insulation and secure coil-to-plug contact.
