Restore high-voltage spark insulation between the coil and plug with the ThunderCore PRO Coil Boot 900-P2071 (also written 900P2071). 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; heat, vibration, and chemical exposure can degrade it over time, and if a worn or cracked boot is the cause of arc-through, misfires, or hard starting, this replaces it. It fits a wide range of GM applications, including the 2006-2010 Chevrolet Cobalt, 2007-2014 Chevrolet Malibu, 2006-2010 Pontiac G6, 2010-2014 Buick LaCrosse, and 2010-2015 GMC Terrain — see the Buyer's Guide tab for the full list of makes, models, and engines.

  • OE Replacement quality: engineered to match OE dielectric strength, boot length, and connector geometry.
  • Restores ignition insulation: replaces a worn or cracked boot to help maintain proper spark isolation and reduce voltage loss.
  • Heat & chemical resistant: built from high-temp silicone and reinforced materials to resist oil, fuel, and under-hood heat.
  • Designed for factory ignition coils and spark plugs in coil-on-plug and coil-near-plug systems.
