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.
