Keep high-voltage spark flowing cleanly from coil to plug with the ThunderCore PRO Coil Boot 900-P2059. It installs as a direct-fit replacement for the 2009-2013 Porsche 911, 2009-2012 Porsche Boxster, 2003-2006 and 2010-2014 Porsche Cayenne, and 2009-2010 Porsche Cayman — see the "Vehicles it fits" section to confirm the engine for your vehicle.
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, providing high-voltage insulation and a secure coil-to-plug connection. Over time boots can degrade from heat, vibration, or chemical exposure, which may lead to arc-through, misfires, or hard starting.
If a failed coil boot is the cause of your misfire or hard-start condition, this boot replaces it to restore proper high-voltage insulation.
