The Spark Plug Wire Heat Shield protects your spark plug wires by withstanding heat up to 2500°F.
Spark Plug Wire Sleeves are 6 inches long with a 0.86 inch inside diameter for 90 degree, 45 degree and straight spark wire sleeves.
The spark plug wire heat shield protects the spark plug sheath and wires from the high temperatures generated by the vehicle's exhaust manifolds and tubes.
Made from two layers of high-temperature titanium, the material is thick enough to protect the spark plug wires from high temperatures as they approach the exhaust manifold, prolonging wire life and maintaining maximum spark effect, withstanding up to 2,500 degrees intermittent heat.
Easily installed by simply slipping the large end (with stitching) over the boot of the spark plug wire and then carefully slipping the looped end over the boot attached to the spark plug.
