ThunderCore PRO Coil Boot Kit P/N:900-P2076-4

Keep high-voltage spark flowing cleanly to every plug with the ThunderCore PRO Coil Boot Kit (MPN 900-P2076-4, also written 900P20764), an OE-replacement kit for coil-on-plug (COP) and coil-near-plug (CNP) ignition systems. It installs as a direct-fit replacement on the 2009-2011 Chevrolet Aveo, 2009-2011 Chevrolet Aveo5, and 2008-2009 Saturn Astra — see the Buyer's Guide tab for engine-specific coverage. 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 may lead to arc-through, misfires, or hard starting. If a worn or cracked boot is the cause of those symptoms, this kit replaces it.

• Heat & chemical resistant: constructed from high-temperature silicone and reinforced materials to resist oil, fuel, and under-hood heat.
• Restores ignition insulation: replaces worn or cracked boots to help maintain proper spark isolation and secure coil-to-plug contact.
• OE-replacement quality: engineered to match OE dielectric strength, boot length, and connector geometry.
• Complete kit coverage: includes the boots, springs, and insulators needed for full-cylinder replacement — ideal for ignition tune-ups or preventative maintenance.
