Walker Products Thunder Core Ultra Ignition Coil Boot

The Walker Products ThunderCore-Ultra ignition coil boot line (also called a coil-on-plug boot or spark plug coil boot) gives you an OE-quality replacement for worn, cracked or brittle boots. The boot carries high-voltage current between the ignition coil and the spark plug. Replacing a failing boot helps restore proper spark isolation and prevents voltage loss.

Key Features:

• OE-quality design: Built to meet or exceed original equipment manufacturer specifications and test requirements.
• RFI suppression: Stainless steel springs with resistors are engineered to suppress radio frequency interference.
• Maximum spark energy: Designed to deliver maximum voltage to the spark plug.
• Weatherproof sealing: Helps keep moisture out of the boot and the spark plug well.
• Heat and chemical resistance: Silicone construction resists under-hood heat, oil and fuel.
• Dielectric grease: Many boots in the line are supplied with dielectric grease to help with installation and connector protection.
• Certified manufacturing: Made in an ISO 9001 / IATF 16949 certified facility.
