Design Engineering Dei Protect-A-Boot Spark Plug

The Design Engineering (DEI) Protect-A-Boot line gives spark plug boots and wires a heat shield against the extreme under-hood temperatures of high-performance engines. These spark plug boot protectors (also called spark plug boot sleeves or heat sleeves) help prevent the burning, cracking, hardening and arcing that heat can cause in plug boots and wires.

Key Features:

• Heat-resistant woven construction with a proprietary coating, for spark plug boot and wire protection from header and engine heat
• Resists chemicals, abrasion and contaminants
• Helps prevent burn-through, hardening and cracking of boots
• Slip-on design that is flexible enough to fit many straight and angled boots
• Titanium carbon fiber-style look that suits race, street, show and off-road engine bays
• Suited to automotive, marine and powersports ignition systems

Design Engineering, Inc. has been a performance heat-management brand since 1995. The Protect-A-Boot line is made for enthusiasts who want longer-lasting ignition components and a clean engine bay. Boot protectors and wire heat shield kits are offered in several configurations, so you can choose the one that suits your engine.
