Six-inch silver Protect-A-Boot sleeves designed to shield spark plug boots and wires from extreme header and engine heat. Made from high-temperature glass fiber material and treated with a special thermal coating, these sleeves protect against burn-through, hardening, and cracking. Each sleeve includes an internal metal reinforcement ring at the base to make plug removal easier during maintenance.

Suitable for most straight or angled spark plug boots. For tight bends, the Ringless version is recommended, and for thick boots such as MSD or Taylor, the Ringless Sleeves offer a better fit due to their larger internal diameter.

• Non-flammable and resistant to chemicals and moisture
• Universal fit for most plug boots
• 1" internal diameter
