Keep cool and lay low with Heatshield Products Stealth Turbo Shield, the black turbo heat blanket you've been waiting for. Retaining heat inside the turbo may lower underhood temperatures up to 40 percent and also reduce chatter and lag, plus it may increase boost (in some applications) and reduce radiant heat damage to other engine components. We use a -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 turbo heat blanket uses the same extreme-heatrated technology as our other turbo shields, but has a cool black stealth appearance. Capable of withstanding 1,800 degrees F continuous, our Stealth Turbo Shield is designed for street performance and hardcore racing applications. The precision-fit design of these turbo shields also means you do not have to trim it to fit your turbo housing, making installation a snap. Turbo removal is not necessary in most cases, and the kit includes stainless steel springs to be used with anchors to hold it in place.
