Keep every spark firing cleanly with the ThunderCore PRO Coil Boot 900-P2037, an OE-replacement boot that restores the high-voltage insulation between the ignition coil and the spark plug. It installs as a direct-fit replacement for coil-on-plug (COP) and coil-near-plug (CNP) applications, covering the 2001-2002 Chevrolet Astra, 2002-2005 Chevrolet Cavalier, 2002-2007 Saturn Vue, 2004-2005 Chevrolet Classic, 2004-2006 Chevrolet Malibu, 2005-2006 Chevrolet Cobalt, and the 2006 Chevrolet HHR, Pontiac G4, Pontiac Pursuit, and Saturn Ion — see the "Vehicles it fits" section for engine-specific coverage.
Over time, coil boots degrade from heat, vibration, and chemical exposure, which can lead to arc-through, misfires, or hard starting. This boot replaces a worn or cracked original to help restore proper spark isolation and secure coil-to-plug contact.
- OE-Replacement Quality: engineered to match OE dielectric strength, boot length, and connector geometry.
- Heat & Chemical Resistant: constructed from high-temperature silicone and reinforced materials to resist oil, fuel, and under-hood heat.
- Restores Ignition Insulation: replaces a worn or cracked boot to help maintain spark isolation and reduce voltage loss.
- Exact OE Fit: designed for coil-on-plug and coil-near-plug ignition systems.

Frequently Asked Questions
What does the ThunderCore PRO 900-P2037 coil boot do?
It serves as the insulative path between the ignition coil and spark plug in coil-on-plug and coil-near-plug systems, providing high-voltage insulation and secure coil-to-plug contact.
What are signs a coil boot may need replacing?
Degraded boots can arc-through, which may cause misfires or hard starting. Cracked, hardened, or oil-soaked boots are common signs; diagnose the cause before replacing, as misfires can have other sources.
Which vehicles does this coil boot fit?
It fits applications such as the 2001-2002 Chevrolet Astra, 2002-2005 Cavalier, 2002-2007 Saturn Vue, 2004-2006 Malibu, 2005-2006 Cobalt, and 2006 HHR, Pontiac G4/Pursuit, and Saturn Ion. Check the "Vehicles it fits" section.
What is the boot made from?
It is constructed from high-temperature silicone and reinforced materials designed to resist oil, fuel, and under-hood heat.
Is this a single boot or a full kit?
This listing is for a coil boot. Confirm the quantity your engine requires and order accordingly for full-cylinder service.
