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.
The spark plug wire sleeve is made of basalt material, which has good resistance to high temperatures and helps prevent the wire sleeve from burning through and hardening.
Using a spark plug wire heat shield protects the performance and extends the life of the spark plug wire set. By reducing the amount of heat transferred to the spark plug wires, the Spark Plug Wire Shield helps improve ignition performance.
