When fiberglass boot protectors failed the demands of Professional Racing, Thermal Control Products introduced a new high temperature Spark Plug Wire Protector. Manufactured of a dual layered composite material and offering a continuous operating temperature of 1800°F, while reflecting 90% of the thermal energy generated in the engine compartment. The heat shield is manufactured with a 45° beveled end, insuring the Spark Plug Boot is fully protected from engine block and header heat.

Our Spark Plug Boots are available in complete wire sets of 4, 6 or 8 pieces, and priced individually below at 9" length.
