Radiator Relief(TM) solves the problem of high engine temps by reducing coolant temperatures up to 30 degrees. Radiator Relief is an excellent method of treating cooling systems as a preventive step to help avoid overheating, electrolytic (electrolysis) and chemical corrosion and is compatible with all coolant additives and anti-freeze mixtures. Both an anti-foaming agent and corrosion inhibitor which balances the negative acidic effects that can develop over time are also included. Radiator Relief is also safe to use with all types of radiator materials including cast iron, copper, brass and aluminum.

Locking Tie tool solves the problem of not being able to get stainless locking ties tight. An effective tool to tighten Stainless Steel Locking Ties. Saves time and hassle while providing a professional looking result. Slide the tool on the end of any 1/4 in. nut driver, engage the tie and twist.

Stainless-Steel Positive Locking Ties secure exhaust wrap and solves the problem of needing a locking tie in high heat areas. Stainless-Steel Positive Locking Ties are designed for high heat applications. With it's self-locking design they are great for securing DEI exhaust wrap to pipes or any place a high strength tie is needed. UV and corrosion resistant they will last for many years under severe use.

Under Carpet Lite solves the problem of engine, exhaust and road heat soaking into interiors. Under Carpet Lite is a superior sound decoupling material for those hard to cover areas like door liners, rear decks, headliners and more. Under Carpet Lite (UC Lite) is a 1/2 in. thick multi-layer, high tech composite material designed to be extremely flexible and easy to install. UC Lite offers maximum thermal insulation in a lightweight padding (approx. 0.23lbs per square foot) that provides less heat transfer in the summer while protecting against the transfer of cold air in the winter.

Turbo Shields solve the problem of extreme underhood heat, stops heat damage of painted or carbon fiber hoods and helps turbos spool faster. DEI recognized the need for new Turbo Shield applications, and now offer Turbo Shields in the smaller turbo sizes. Unlike cheap, knock-off copies, DEI Turbo Shields use an exclusive combination of premium heat resistant textiles and newly designed stainless steel attachment anchors.

Turbo Shields solve the problem of extreme underhood heat, stops heat damage of painted or carbon fiber hoods and helps turbos spool faster. Custom fit Titanium Turbo Shields(TM) provide the ultimate means of reducing turbo lag and serve as a superior heat barrier. Titanium Turbo Shields can withstand direct heat up to 1800F and 2500F radiant heat. Allowing more heat in the turbine and less damaging underhood radiant heat resulting in a boost in horsepower!
