Plug wire boots sitting inches from a set of headers eventually pay the price, cracking or burning through long before the wire itself fails. DEI's Protect-A-Boot sleeves slip over the boot to absorb that radiant heat instead, buying the ignition system real protection where it's most exposed.

• High-temperature resistant fiberglass material.
• Withstands up to 1,200 degrees F of direct, continuous heat.
• Helps prevent burn-through, hardening and cracking of boots.
