Keep high-voltage spark energy where it belongs with the ThunderCore PRO Coil Boot 900-P2005, an OE-replacement boot that restores the insulative path between the ignition coil and the spark plug. It's a direct-fit replacement for a wide range of BMW models, including the 1992-1997 and 2001-2002 325i, 1996-2000 328i, 2001-2002 330i, 1996-2000 528i, 1997-2003 540i, 1993-2001 740iL, 1999-2003 M5, 2000-2003 X5, 1997-2002 Z3, and 2000-2003 Z8 — see the Buyer's Guide tab for the full list of applications and engines.
A coil boot sits between the coil and the plug and can degrade over time from heat, vibration, or chemical exposure, which can lead to arc-through, misfires, or hard starting. If a failed boot is the cause of those symptoms, replacing it with the 900-P2005 helps restore secure coil-to-plug contact and proper high-voltage insulation on the listed BMW applications.
