ThunderCore PRO Coil Boot P/N:900-P2039
Keep high-voltage spark reaching the plug with the ThunderCore PRO Coil Boot 900-P2011, an OE-replacement boot for coil-on-plug (COP) and coil-near-plug (CNP) ignition systems. It drops in as a direct-fit replacement for the 1997-2000 Audi A4 Quattro, 1998-1999 Volkswagen Passat, 2000-2002 Audi A6 Quattro, 2000-2002 Audi S4, and 2001-2002 Audi Allroad Quattro — see the Buyer's Guide tab for engine-level fitment.
In COP and CNP setups the coil boot forms the insulative path between the ignition coil and the spark plug. Over time boots can degrade from heat, vibration, or chemical exposure, which can lead to arc-through, misfires, or hard starting. If a worn or cracked boot is the cause, this part restores that spark isolation.
