Restore reliable spark insulation with the ThunderCore PRO Coil Boot 900-P2020. This OE-replacement boot serves as the insulative path between the ignition coil and the spark plug in coil-on-plug (COP) and coil-near-plug (CNP) ignition systems, and it drops in as a direct-fit replacement for the 2000-2005 Volvo S80, 2001-2004 Volvo S60, 2001-2004 Volvo V70, 2003-2004 Volvo XC90, and 2005-2006 Volvo S40 — see the Buyer's Guide tab for engine-level details.
- OE Replacement Quality: engineered to match OE dielectric strength, boot length, and connector geometry.
- Restores ignition insulation: replaces worn or cracked boots to help maintain proper spark isolation and reduce voltage loss.
- Heat & chemical resistant: constructed from high-temp silicone and reinforced materials to resist oil, fuel, and under-hood heat.
- Exact OE fit: designed for compatibility with factory ignition coils and spark plugs in COP and CNP setups.
Over time, coil boots degrade from heat, vibration, and chemical exposure, which can lead to arc-through, misfires, or hard starting. If a worn or cracked boot is the cause of those symptoms, replacing it helps restore high-voltage insulation and secure coil-to-plug contact. Diagnose the cause before replacing, since misfires can have other sources.
