The Turbo Kit was designed to protect, improve performance, and minimize turbo lag on turbo chargers. This complete kit fits a wide variety of turbines. The custom cut-to-fit kit comes with an excessive amount of material to cover turbos in anything from the smallest car to a heavy-duty truck. Two kits are available - a four cylinder kit, and a six and eight cylinder kit. Each kit contains a roll of exhaust insulating wrap (1 inch with 4 cylinder kit, 2 inch with 6 & 8 cylinder kit), 1 yard of aluminized heat barrier, and a 3 inch X 6 inch piece of exhaust insulating wrap. Hardware and instructions are included.
