The HP Lava turbo heat shields were designed for and tested on the most hardcore racing applications. Lava Turbo Heat Shield reduces turbo lag while protecting other engine components and reducing under hood temperatures. The turbo heat shields are custom fit and use extreme temperature materials to keep heat in the hot side of the turbo where it belongs. The Lava Turbo Shield has a rugged outer layer of Their Lava Mat that is 25 percent stronger than comparable fiberglass shields, giving them a longer life span. The silica contact layer and silica insulation, make the turbo shield capable of withstanding 1800F continuously. The custom fit design means you do not have to trim or fit the heat shield blanket to fit your turbo housings making installation a snap.
