Design Engineering Dei 10540 Protect-A-Boot Spark Plug Boot Protector Titanium - 8 Inch 6-Pack

The Design Engineering Dei Protect-A-Boot is a high-performance spark plug boot and wire protector designed to shield ignition components from extreme heat. This 8-inch titanium-finish sleeve protects spark plug boots and wires from radiant heat damage that can cause misfires, rough idle, and premature failure of ignition components.

Key Features:

• Reflects up to 90% of radiant heat away from spark plug boots and wires
• Constructed from flexible, heat-resistant silicone material with titanium finish
• 8-inch length provides extended coverage for longer wire runs
• Withstands continuous temperatures up to 500°F and intermittent temperatures to 650°F
• Easy slip-on installation with no special tools required
• Prevents heat-related cracking, hardening, and electrical failures
• Six-piece pack provides protection for 6-cylinder applications or spares

Ideal for engines with headers, turbochargers, or where spark plug wires run near exhaust components. The Protect-A-Boot helps maintain reliable ignition performance and extends the service life of expensive plug wires and boots. Perfect for high-performance, racing, and street applications where heat management is critical.
