3. Ignition Protection

Electrical components react to heat, and elevated levels in the ignition system can lead to a multitude of problems from misfiring and arcing, to breakdown of the materials themselves. Direct contact with extreme heat can burn plug wires and instantly cause arcing, resulting in a loss of both fuel economy and power.

DEI Titanium Protect-A-Sleeve

DEI uses the same lava rock (LR) weave found in their exhaust wrap to create extremely effective and good looking plug wire sleeves. Developed specifically for any application where extreme high heat is present, these sleeves will protect wires, lines, and cables when exposed up to 1,800 degrees F direct heat or 2,500 degrees F radiant heat. The ½-inch id sleeves will fit most large diameter spark plug wires. Matching plug boots are also available.

Thermo-Tec Cool-It Plug Wire Sleeves

These sleeves from Thermo-Tec feature a double-wall construction that keeps the wire and boot significantly cooler in a high-temperature engine. Keeping the plugs cooler helps enhance performance, reduce misfires, and extend plug wire life. The proprietary material is nonflammable and will not react with petroleum products. Multiple color choices also allow you to color coordinate with your existing engine dress or ignition brand.

HSP Distributor Shields

Heat Shield Products (HSP) has been developing a line of component-specific sleeves like this Distributor Shield. HSP says it will not only improve a distributor's performance but also increase its lifespan by reflecting damaging radiant heat away. Capable of withstanding 1,100 degrees F of radiant heat and 500 degrees F of direct heat, this jacket is ideal for track days. The universal size with an adjustable hook and loop seam makes it work for any application.


4. Cooler Oil

Oil in a mechanical system is not only for lubrication, it works as a heat sink as well. Even the best oils, however, have an operating zone at which they are most effective. Exceed it and you're asking for breakdown of the protective film and a loss of protection. Cooler oil will lead to longer change intervals, greater longevity for the systems they are lubricating, and less thermal stress on all the components in your engine and engine compartment.

Derale Atomic-Cool Remote Cooler

While Derale does offer unpowered coolers, the company's remote mountable coolers pack their own air supply for cooling, no matter what the location. A favorite of ours, this popular Atomic-Cool Remote Engine Oil Cooler can be mounted nearly anywhere, making it a popular addition for engine, steering, and transmission cooling in hot rods, muscle cars, and trucks. A heavy-duty plate and fin cooler is coupled with a Tornado fan that is operated by a 180-degree F inline thermostat.

Earl's Temp-A-Cure

Standard serpentine-style tube and fin coolers have a large pressure drop due to the tube length and restrictive bends. To avoid that and increase efficiency in extreme conditions, Earl's Temp-A-Cure coolers are a modular design like those found on Formula One, IndyCar, and GTP/Trans-Am–style cars. The internal design of the oil tubes and the large area collector tanks provide maximum surface area with minimal pressure drop, while the highly concentrated air fins offer maximum heat transfer to the air.


5. Hose Wraps

Hose wraps can work in two different ways: to protect the hoses and their contents from heat, and to protect you from the heat contained within them. We've used this type of product before, even testing (OK, torturing) them with prolonged, direct flame from a butane lighter. This category of stuff is practically impervious to anything short of nuclear fission, and is most effective at protecting fluid lines and electrical connections from extreme exhaust heat.

DEI Fire Sleeve 3000

Constructed from a high-temperature–resistant braided glass material woven into a sleeve and heavily coated with 100 percent iron oxide silicone rubber, DEI's Fire Sleeve 3000 provides insulation and protection from 500 degrees F continuous and 2,000 degrees F intermittent heat. Kits also include a 16-inch length of black Fire Tape to finish off ends of Fire Sleeve or when joining two Fire Sleeves together while presenting a clean and professional look. Fire Sleeve is available with and without a hook and loop clasp design depending on your install needs.

Thermo-Tec Thermo-Sleeve Express

Created from a seamless lamination of a high-temperature fabric to a highly reflective foil, Thermo-Sleeve works to prevent radiant heat from overheating hoses and wires. The aluminized sleeving reflects over 90 percent of radiant heat up to 2,000 degrees F, it can withstand direct continuous temperatures up to 750 degrees F, and it's both fireproof and oil resistant. Plus, Thermo-Sleeve is ultra lightweight and can provide as much insulation as heavier products. Fastened with Velcro, it's easy to apply these sleeves before or after plumbing and wiring.

Heat Shield Products Thermaflect

Thermaflect Sleeve acts as a thermal barrier capable of reflecting up to 90 percent of radiant heat, provided it has a minimum of 1 inch of separating airspace and good airflow. It also weighs a fraction of what silicon-coated sleeves do, and it offers matching radiant heat insulation. Thermaflect Sleeve withstands 1,100 degrees F of continuous radiant heat and 500 degrees F direct heat. For convenience of maintenance, it's also available in a hook and loop seam.


6. Thermal Barriers

This is the largest category within the framework of heat control and contains far more products and applications than we can possibly cover here. It's also one of the most effective zones since it focuses not only on managing heat away from critical components, but away from the passengers as well.

Design Engineering Inc.

We actually have three Design Engineering Inc. (DEI) products here. On top, Under Carpet Lite is a sound-decoupling material for those hard-to-cover areas like door liners, rear decks, and headliners. It offers thermal insulation in a lightweight padding that provides less heat transfer in the summer while protecting against the transfer of cold air in the winter.

In the middle is Boom Mat Undercarpet, a second layer of sound deadening and insulation mat that will prevent noise transfer into the vehicle's interior. As a two-layer acoustic material, Boom Mat not only kills noise and rattles, it also provides insulation to keep vehicles cool in the heat of summer, and warmer in cold temperature climates.

The thin layer on the bottom is Boom Damping Material. A very thin viscoelastic polymer layer protected by a durable aluminum wear surface can be applied to horizontal, vertical, and inverted areas on metal, plastic, fiberglass and most other automotive surfaces to fight NVH, as well as reject extreme hot and cold temperatures.
