The Thermo-Tec Turbo Kit was designed to protect, improve performance, and eliminate turbo lag of a turbo charger. The key to turbo performance is to keep a flow of high temperature exhaust gases moving through the exhaust side impeller. This complete kit, to contain the heat produced by a turbo, fits a wide variety of turbines. The custom cut-to-fit kit comes with an excessive amount of material to cover turbos from the smallest automotive application to heavy-duty truck applications.
