Custom fit Onyx (Black) Turbo Shields provides the ultimate means of reducing turbo lag while serving as a superior heat barrier - shielding and protecting engine components, hoods and painted surfaces and offers a very cool looking carbon fiber look. Made from pulverized volcanic rock then strained into a fiber material, Titanium Turbo Shields can withstand direct heat up to 1800 F and 2500 F radiant heat. This means retaining more heat in the turbine and less damaging under hood heat. The result is a cooler air intake temperature and a boost in horsepower! Stronger and more durable than other turbo blankets or shields, Titanium Turbo Shields include a hi-temp rated silica insulation padding under the tight outer layer for extra added protection against extreme turbo-generated heat.
