Some more info about the DEI T3 turbo blanket
Custom-fit DEI Titanium turbo shields with LR Technology provide the ultimate means of reducing turbo lag while serving as superior heat barriers. They shield and protect engine components, hoods, and painted surfaces and offer a very cool carbon fiber look. Made from pulverized volcanic rock and then strained into a fiber material, Titanium turbo shields can withstand direct heat up to 1,800 degrees F and radiant heat up to 2,500 degrees F. This means retaining more heat in the turbine and less damaging under hood heat. The results are a cooler air intake temperature and a boost in horsepower! Stronger and more durable than other turbo blankets or shields, DEI Titanium turbo shields include high-temperature rated silica insulation padding under a tight outer layer for extra-added protection against extreme turbo-generated heat.
