ThunderCore PRO Coil Boot P/N:900-P2077

$12.99

Description

Keep high-voltage spark flowing cleanly from coil to plug with the ThunderCore PRO Coil Boot (P/N 900-P2077), an OE-replacement direct fit for the 1999-2001 Cadillac Catera and 2003-2004 Cadillac CTS — see the Buyer's Guide tab for engine-specific coverage. In coil-on-plug (COP) and coil-near-plug (CNP) ignition systems, the coil boot serves as the insulative path between the ignition coil and the spark plug. Over time, heat, vibration, and chemical exposure can degrade a boot, leading to arc-through, misfires, or hard starting — if a worn or cracked boot is the cause, this replaces it to help restore proper spark isolation and secure coil-to-plug contact.

Restores ignition insulation: replaces worn or cracked boots to help maintain proper spark isolation and limit voltage loss.
OE fit: designed to match factory ignition coils and spark plugs for COP and CNP systems.
OE replacement quality: engineered to match OE dielectric strength, boot length, and connector geometry.
Heat & chemical resistant: constructed from high-temp silicone and reinforced materials to resist oil, fuel, and under-hood heat.
