Durable Construction: These spark plug wire heat shields are made from woven alkali-free fiberglass tubing, creating a durable thermal barrier that withstands continuous temperatures of 1200°F–1800°F and short-term exposure up to 2500°F. This effectively protects spark plug wires and boots from extreme engine and exhaust heat
Keep Performance: By shielding ignition wires and spark plug boots from excessive heat and chemical exposure, these sleeves help prevent misfires, maintain consistent engine performance, and significantly prolong the service life of your spark plug wiring system
Universal Fit: With a 6.1 inch length, these spark plug heat shield sleeves are compatible with 90°, 45°, and straight spark plug boot designs. They fit a wide range of classic and performance engines, including Chevy, Ford, Dodge, and GM small-block and big-block applications
Easy Installation: Designed for tool-free installation, simply insert the sewn end of the sleeve into the spark plug boot first, then gently slide it over the wire harness. The flexible fiberglass material allows for a secure, custom fit without requiring modifications or additional hardware
Complete Kit: Each package includes eight heat shields, providing full coverage for V8 engines or offering spares for other configurations. The set is ideal for hot rods, classics, modified engines, and daily drivers operating in high-temperature environments
