The hoses are designed to improve air flow by not allowing the hoses to expand under boost pressure. Like a brake line, when under pressure, the factory hoses can expand. The silicone tube keeps the structural integrity thus not changing boost pressure and keeps your power up. The factory rubber hoses can deteriorate over time and even blow out! These boost hoses have been tested to over 30psi. The boost hoses are available in red, black, blue, silver, and yellow. Hoses are designed to fit all Porsche 996TT from 01-05.
