Cool-It Plug Wire Sleeve 4 Pack Red

The Cool-It Plug Wire Sleeve 4 Pack Red from THERMO-TEC is an essential heat management solution for engine builders and performance enthusiasts working in high-temperature underhood environments. These sleeves are designed to protect spark plug wires from the damaging effects of heat near exhaust manifolds, cylinder heads, and turbo components, which can lead to ignition misfires and engine damage.

Constructed from high-temperature silicone, these sleeves provide a thermal barrier that reflects radiant heat away from the wire's conductive core, preventing insulation breakdown and arcing. The flexible design allows for easy installation without the need to disassemble spark plug or wire terminals, making them user-friendly for various applications.

Ideal for street rods, daily drivers, and track engines, the Cool-It sleeves enhance wire lifespan and maintain consistent spark delivery under extreme conditions. The 4-pack quantity is suitable for most V-8 applications, offering redundancy for modifications and replacements, ensuring reliable performance in demanding environments.
