Protect-A-Boots are made from a high temperature resistant glass fiber material and treated with a proprietary coating, Protect-A-Boots provide spark plug boot and wire protection from extreme under hood heat and helps prevent burn-through, hardening and cracking of boots. Our 6'' Protect-A-Boots come with a reinforcement ring at the base for easy plug removal during maintenance. When working on boots with tight bends, try our Protect-A-Boots Ringless instead.
