Walker Products ThunderCore Ultra Premium Coil on Plug Boot Kit

The Walker Products ThunderCore Ultra Premium Coil on Plug Boot Kit line offers OE-replacement coil boots. They restore spark isolation and a secure electrical connection in coil-on-plug (COP) and coil-near-plug (CNP) ignition systems. Over time, heat, vibration and chemical exposure can degrade the boots. That can cause arc-through, misfires and hard starting. Replacing them helps restore ignition reliability.

Key Features:

• Engineered to match OE specifications for dielectric strength, boot length and terminal fitment
• Provides a secure coil-to-plug connection and proper high-voltage insulation
• Made from premium high-temperature silicone and reinforced materials that resist under-hood heat, oil and fuel
• Stainless steel springs with resistors help suppress radio frequency interference (RFI)
• Weatherproof seal helps keep moisture out
• Dielectric grease is included for installation
• Built in an ISO 9001 / IATF 16949 certified facility to meet or exceed OEM specifications and test requirements

Walker Products has decades of ignition system experience, dating back to 1946. ThunderCore Ultra coil boots suit ignition tune-ups, preventative maintenance and targeted coil boot repairs. They help restore engine smoothness and emissions performance.
