Heatshield Products Lava Turbo Shield™ was designed for and tested to manage heat on the most hardcore turbocharged racing applications.Heatshield Products Lava Turbo Heat Shield™ reduces turbo lag while protecting other engine components and reducing underhood temperatures. Lava Turbo Heat Shield™ is a custom fit and uses extreme-temperature materials to keep heat in the hot side of the turbo where it belongs. The Lava Turbo Heat Shield™ has a rugged outer layer of our Lava Shield™ material that is 25 percent stronger than comparable fiberglass shields, giving a longer life span. The silica contact layer and silica insulation make Lava Turbo Heat Shield™ capable of withstanding 1,800 degrees F continuous. We use a 1/2-inch-thick BioCool thermal-barrier inner pad sandwiched between heavy-duty foil, bound and sewn together with a stainless steel mesh at the edges. BioCool is a non-caustic, non-flammable thermal barrier. The precision-fit design means you do not have to trim or fit the heatshield blanket to your turbo housing, making installation a snap.
