What Are Spark Plug Heat Sleeves?

Spark plug Heat sleeves are high-temperature basalt or fiberglass sleeves designed to fit over the spark plug boot. Their primary function is to insulate the boot from heat, ensuring it maintains a firm seal and doesn’t crack under pressure. Additionally, these sleeves act as a barrier against dirt, moisture, and contaminants, all of which can negatively impact spark plug performance.

Why Choose Kool Wrap Sleeves?

Superior Heat Protection

One of the standout features of Kool Wrap’s spark plug heat sleeves is their exceptional heat resistance. Engines, particularly high-performance and turbocharged ones, generate extreme heat that can quickly damage standard boots. Fortunately, our sleeves are engineered to withstand intense temperatures, protecting both the spark plugs and ignition coils from heat-related damage. As a result, this protection helps maintain the integrity of your ignition system and prevents misfires, which could otherwise reduce engine performance.

Moisture and Contaminant Protection

Off-road and harsh driving conditions can expose your engine to moisture, dirt, and oil. These contaminants, over time, can cause corrosion and disrupt the ignition system’s functionality. Kool Wrap’s sleeves snugly fit around the spark plug boot, providing an effective shield against heat and debris. By keeping these elements out, our sleeves extend the life of your spark plugs and ensure smooth engine performance, even in tough environments.
