Insul-Boot™ spark plug boot heat socks protect plug wires from ambient heat exposure and damage up to 1,200 degrees F, extending wire life while also increasing ignition-system performance through reduced wire resistance. Insul-Boot™ prevents misfires caused by plug-wire burnout, helping prevent critical engine damage and performance losses. The double-wall construction provides superior ambient heat protection, while special coatings reflect and dissipate heat. The universal design fits most spark plug boot angles, and Insul-Boot™ is available in six ceramic colours: red, blue, black, tan, yellow and orange. Installation is easy and will not hinder spark plug changes.
