Heat is one of the biggest challenges your engine faces every time you start your vehicle. Excessive temperatures around spark plug wires can cause misfires and wear down critical components faster than you expect. Thermo-Tec’s Cool-It Plug Wire Sleeves provide an easy solution by insulating your spark plug wires, helping to keep them cooler and improving overall ignition performance so your engine runs more reliably and efficiently.
Measuring 6 inches in length and 1.25 inches in thickness, the sleeves are sold in sets of four to cover your entire ignition system. Plus, their universal fit means they can easily slide over nearly any plug wire and boot, whether you're working on a high-performance car or a larger vehicle like an RV, ensuring broad compatibility without hassle. Choose between a sleek Black or vibrant Blue finish to match your style.
Constructed with a robust double-wall design, the Cool-It Plug Wire Sleeves protect your wires and boots from extreme heat on both sides. Crafted from a high-heat-tolerant material rated up to 750 degrees Fahrenheit, these sleeves resist flames, oil and other harsh automotive fluids. Proudly made in the U.S., Thermo-Tec backs these sleeves with a 100% Satisfaction Guarantee so you can trust in the quality and effectiveness of the product.
