These insulating sleeves protect your spark plug wires and boots from damaging engine heat. The double layer of woven fiberglass resists heat up to 1200° F. They can even rest directly on the exhaust header without damage. Non-conductive and non-combustible material resists harsh engine chemicals and degreasers*. Approximately 7 1/2" Long x 3/4" ID sleeves are flexible to fit most boots, even 90°. Sold individually.
* Note: The woven material is porous and will provide only limited protection to the plug wires against liquids.
