ThunderCore PRO Coil Boot Kit P/N:900-P2023-6

Restore reliable spark insulation with the ThunderCore PRO Coil Boot Kit (P/N 900-P2023-6), an OE-replacement kit for the 1995-2002 Mazda Millenia. In coil-on-plug (COP) and coil-near-plug (CNP) ignition systems, 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 can lead to arc-through, misfires, or hard starting. If worn or cracked boots are the cause, this kit replaces them to help restore proper spark isolation and secure coil-to-plug contact.

• Heat & chemical resistant: constructed from high-temp silicone and reinforced materials to resist oil, fuel, and under-hood heat.
• Restores ignition insulation: replaces worn or cracked boots for proper spark isolation and to help prevent voltage loss.
• Full-cylinder kit coverage: includes the boots, springs, and insulators for full-cylinder service, suited to ignition tune-ups and preventative maintenance.
• OE-replacement quality: engineered to match OE dielectric strength, boot length, and connector geometry.

Designed for the factory ignition coils and spark plugs of the listed application. See the Buyer's Guide tab to confirm the engine and coil configuration for your vehicle.
