The spark plug boots on a factory vehicle insulate the connection between the spark plug and the ignition wire, and they do a great job. However, they’re not designed for the challenges of a high performance engine. As spark energy and underhood heat rise, stock boots can melt down.
Spark plug boot protectors add a layer of safety to your ignition system. Some protectors are metal shields that snap on over the boot, while others are flexible sleeves that slide on. Whichever style you choose, they’ll protect your wires from heat and help prevent arcing.

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.
