Walker Products 900-P2096-4 Thunder Core Ultra Ignition Coil Boot - Kit

The Walker Products 900-P2096-4 Thunder Core Ultra Ignition Coil Boot Kit is a premium OE-replacement coil-on-plug (COP) boot kit designed to restore reliable spark isolation and high-voltage electrical connection in modern ignition systems. This 4-boot kit delivers everything needed for full-cylinder service on 4-cylinder coil-on-plug and coil-near-plug (CNP) applications.

In COP and CNP ignition systems, coil boots serve as the critical insulative path between the ignition coil and the spark plug. Over time, boots degrade from heat, vibration, and chemical exposure, leading to arc-through, engine misfires, and hard starting. Walker's Thunder Core Ultra boots are precision-engineered to match OE dielectric strength, boot length, and terminal fitment for proper high-voltage insulation and a secure coil-to-plug connection.

Key Features:

• 4-boot kit — includes all boots, springs, and insulators for complete 4-cylinder service
• Stainless steel springs with built-in resistors engineered to suppress Radio Frequency Interference (RFI)
• High-temperature silicone construction resists oil, fuel, and under-hood heat
• Weatherproof seals minimize moisture and condensation accumulation
• Engineered to maximize voltage delivery to the spark plug
• Meets and exceeds OEM specifications for dielectric strength, length, and connector geometry
• Precision manufactured in an ISO 9001/IATF 16949 certified facility
• Package includes dielectric grease

The Walker Products 900-P2096-4 Thunder Core Ultra kit is ideal for ignition tune-ups or preventative maintenance, helping restore engine smoothness, ignition reliability, and emissions performance. Backed by Walker Products' limited warranty against defects in materials and workmanship.
