Oil filters soak in a lot of heat from high performance engines, as they're nestled tight to the oil pan and engine. DEI's oil filter heat shields effectively block radiant heat that can change the oil's viscosity—or potentially cause a thermal breakdown that will make the oil additives degrade, dissipate, and wear out quickly. These easy-to-install oil filter covers block that heat and reduce oil temperatures, and their universal trim-to-fit sizes will work on any oil filter.

DEI oil cooler line heat shrouds greatly reduce oil temperature. They're made from a high-temperature rated glass fiber fabric with an aluminized outer facing. The shrouds easily wrap around the oil cooler lines without disconnecting the lines, making installation fast and easy. If your oil cooler lines are in close proximity to the catalytic converter—which produces 1,200+ degrees F, especially on the racetrack being pushed to its limits—DEI shrouds will greatly reduce harmful radiant heat soaking into the oil cooler lines. Otherwise, engine oil overheating can cause your vehicle to go into "limp mode." When failure is not an option, ensure top performance with DEI oil cooler line heat shrouds!

DEI Chill Charger is a revolutionary new high performance additive to improve the efficiency of water-to-air intercoolers. Simply add Chill Charger to the intercooler reservoir, and it will enhance the thermal transfer of hot intake air to the water circulating through the intercooler, resulting in a cooler, denser intake charge for a boost in performance. Both turbochargers and superchargers generate a tremendous amount of intense, power-robbing underhood heat. The challenge is to produce lower intake temperatures to maximize output. Chill Charger is a proven additive that reduces water-to-air intercooler temperatures to improve efficiency for maximum performance. DEI Chill Charger is formulated with a corrosion inhibitor that balances and stabilizes the pH level to protect the core from rust, electrolysis, and mineral deposits. Chill Charger also contains an anti-foaming agent, is safe with all intercooler alloys, and is 100 percent biodegradable, non-corrosive, and non-toxic.

Radiator Relief for diesels is a specially formulated performance coolant additive that is concentrated to enhance today's large-capacity diesel cooling systems, and blended for extreme use. Radiator Relief for diesels reduces the surface tension of diesel engine coolant and maximizes the transfer of heat more efficiently from the engine to the radiator. In addition, with its special anti-foaming agent, it promotes superior coolant contact in the cylinder head to accelerate the heat transfer process. Adding DEI Radiator Relief for diesels allows engines to run up to 30 degrees cooler and reduces engine wear, which occurs during extreme temperatures and under heavy loads, such as when towing and climbing hills. Radiator Relief for diesels includes a corrosion inhibitor that balances the negative acidic effects that can develop over time in antifreeze and water solutions. It also stabilizes the pH level, which helps reduce rust and prevent electrolysis, mineral deposits, and pre-existing scale buildup from forming on the radiator, resulting in potential core damage. Radiator Relief for diesels is compatible with all types of water and antifreeze mixtures. It is also safe with all alloys (including aluminum), and is water soluble, 100 percent biodegradable, non-corrosive, and non-toxic.

DEI titanium exhaust wrap with LR technology is constructed from pulverized lava rock, extruded into fibers, and then woven into a tight weave, giving it titanium-like strength and toughness. The improvement in thermal protection helps to reduce underhood temperatures, resulting in cooler air intake for improved performance. And less heat in the engine bay means less chance of heat soak conditions on vital underhood components. Typical glass fiber wrap is rated at handling 1,200 degrees F of maximum direct heat, while DEI's titanium wrap, using LR technology, is capable of handling direct continuous heat up to 1,800 degrees F and radiant heat up to 2,800 degrees F. And because it's pliable, there's no need to wet the wrap when wrapping headers or pipes, as many do in order to make the wrapping process easier to manage and to get a tight wrap. Titanium wrap will not shrink, and because of its material structure, it is more resistant to temperature and vibration breakdown, abrasions, chemical and hot oil spills than glass fiber wrap. Plus, DEI titanium wrap offers a very cool carbon fiber look as an added feature!
