Stick-On Heat Barrier
Applying the same technology throughout the Thermo-Tec line is this adhesive-backed heat barrier. These sheets can be cut to fit and applied virtually anywhere you need protection from heat. They can be cut into strips and wrapped around hoses or even wire looms. The sheeted barriers come in four sizes.
For the ultimate in wire and hose protection, a Thermo-Sleeve is the way to go. It's a combination of high-temperature fabric laminated to a highly reflective Mylar foil. The sleeves are ultra-lightweight and provide more protection than traditional rubber-coated fiberglass. Moreover, they are fireproof and oil-resistant, which makes them perfect for fuel lines or wet sump lines.
Protect those hard-to-reach places around hoses and wires with Thermo-Shield tape. It is adhesive-backed, so all you have to do is wrap it and forget. The tape can prevent vaporlock on heated fuel lines. As usual, it's good for up to 2,000 degrees and is available in 15- and 50-foot rolls.
Heat and vibration can literally destroy a battery, so batteries must be protected. Using a combination of materials, the battery wrap can neutralize battery acid (black felt), and the adhesive-backed heat barrier protects the insides of the battery from heat. These are constructed of woven silica with a flexible aluminized finish.
Wire sleeves are the perfect upgrade. They keep spark plug boots cooler, and that translates to enhanced performance and reduces misfires. They don't react with petroleum products, making them safer, nonflammable, and easy to install.
For late-model owners like the LS1 enthusiasts, keeping the air intake tube leading to the throttle body cooler translates to more power. The unique lace-up design allows the shield to fit 2 1/2- to 3 1/2-inch-diameter tubes up to 3 feet long, and blocks over 90 percent of underhood heat.
