For decades, Techflex’s Insultherm sleeving has been the first choice among automotive professionals and enthusiasts alike for many of their thermal protection applications. Innovative Techflex Insultherm spark plug boot insulators offer the same high-temperature protection that extends the life of expensive spark plug wires by protecting them where they need it most … at the boot. Just slip these insulators over any spark plug cable and boot (even right angle boots). Once installed, they require no clearance from hot surfaces, and can even rest directly on hot exhaust headers without affecting performance. Techflex Insultherm spark plug boot insulators are completely non-conductive and will not support combustion. They provide an easy, economical solution to the challenge of wire protection in cramped, high-temperature, high performance engine compartments. Other features of Techflex Insultherm spark plug boot insulators: * Braided fiberglass construction * Protects up to 1,200 degrees F * 3/4 in. diameter double-thickness (triple-thick at the sewn end) * Halogen-free * Resists gasoline and engine chemicals
