Protect your ignition system with the Heat Protection Products Spark Plug Heatshield Insulation Boot Set, designed to help extend the life of your spark plug wires and boots in high heat environments. These universal heat shields are made with a double wall construction and special heat reflective coatings that work to reflect and dissipate radiant heat away from the boot, helping reduce the risk of burnout, cracking, and performance loss.

With a 1 inch internal diameter, this 8 piece set is designed to fit most spark plug boots, including many 90 degree boots, making it a versatile choice for a wide range of vehicles and engine setups. The fawn finish offers a clean, understated look while the durable insulation is built to withstand continuous temperatures up to 1200°F or 650°C, making it suitable for demanding applications where heat protection is critical.

Installation is simple, with the ring end placed over the spark plug boot and the open end slid toward the wire. Whether you are replacing worn protection or upgrading your ignition components for better thermal resistance, these boot shields help minimise misfires and support more reliable engine performance.
