Enhance your Audi C7 S6/S7/RS7 or D4 A8/S8 4.0T by installing our specially crafted 4-ply Silicone Turbo Outlet Hose Set. Our in-house designed hoses are engineered to replace the original factory turbo outlet and throttle body inlet hoses. Over time, the factory rubber hoses in your 4.0T vehicle tend to become brittle and develop cracks, leading to a loss of boost pressure and vacuum leaks. Our Silicone Hose Set not only fits seamlessly into the factory hose's place but also boasts resistance against oil, fuel, and ozone deterioration.
