The First Boot Protection Company

We were the first to develop spark plug boot protectors, and our Lava Boots continue that legacy with the same high-quality engineering. Each boot features a metal ring to keep it securely in place, preventing it from sliding up the wire and leaving the spark plug exposed—all wrapped in a rugged, crushed volcanic rock sleeve for superior heat protection.

Premium Quality US Made Protection

Heatshield Products Lava Boot feature a no-fray cuff with a flexible dual wall high-temperature basalt sleeving with a 1,200-degree F working temperature that prevents plug and wire burnout even in the most demanding ambient heat applications. Lava Boots help eliminate misfires caused by plug-wire and spark plug boot heatshield burnout, helping prevent critical engine damage and loss in performance from a cylinder not firing. In addition, Lava Boots protect your wires and boots from being damaged by excessive engine and exhaust heat. The universal design fits most boot sizes and angles, including 90-degree boots.
