DEI

Heat is one of the biggest enemies in an engine bay with more power. DEI makes heat protection for cars, motorcycles and ATVs, keeping hoses, wiring and intakes cooler and the cabin less hot. Here you’ll find exhaust wrap, heat shields, protective sleeving, reflective tape and sound and heat insulation.

American heat management specialist

DEI, Design Engineering Inc., is an American brand that has made heat management its speciality. The range is developed for motorsport and tuning, but is used just as much in everyday project cars, pickups and motorcycles. The idea is simple: when heat from the exhaust and turbo is kept where it belongs, surrounding components last longer, intake air stays cooler and the cabin is more comfortable. DEI products are designed so enthusiasts can fit them themselves in the garage.

DEI’s key products

Exhaust wrap is wound around the manifold and exhaust pipes and keeps the heat inside the system. Heat shields and reflective tape protect intakes, fuel lines, brake cylinders and electronics from radiant heat. Protective sleeving slides over hoses and wiring, while insulation mats for the floor, tunnel and firewall reduce both heat and noise in the cabin. DEI also offers turbo blankets and starter heat shields. See each product for dimensions and temperature rating.

Frequently asked questions

What does exhaust wrap do?

Exhaust wrap keeps heat inside the manifold and exhaust pipes. It lowers engine bay temperatures and protects nearby parts. The wrap is wound tightly with an overlap and secured with stainless steel ties.

Which heat protection should I choose for hoses and wiring?

For hoses and wiring close to heat sources, protective or reflective sleeving is often the easiest choice. For larger surfaces, such as under an intake or at the firewall, a heat shield or reflective tape is a better fit.
