Restore reliable spark insulation across all eight cylinders with the ThunderCore PRO Coil Boot Kit (P/N 900-P2095-8). This 8-pack drops in as an OE-replacement for the 1998-2000 Lexus GS400 and 1998-2000 Lexus LS400, both built with the V8-4.0L engine. In coil-on-plug (COP) and coil-near-plug (CNP) systems, the coil boot forms the insulative path between the ignition coil and the spark plug. Over time boots can degrade from heat, vibration, and chemical exposure, which may lead to arc-through, misfires, or hard starting.
OE Replacement Quality: engineered to match OE dielectric strength, boot length, and connector geometry.
Fit for COP/CNP systems: designed to work with the factory ignition coils and spark plugs.
Heat & chemical resistant: rubber construction built to resist oil, fuel, and under-hood heat.
Ignition insulation: replaces worn or cracked boots to help maintain proper spark isolation and limit voltage loss.
Full-cylinder coverage: 8-pack sized to service all eight cylinders, ideal for a tune-up.
Standard Replacement grade, black, rubber. Mounting hardware is not included. Country of origin: Taiwan. Manufacturer part number 900-P2095-8.
