This kit replaces the four charge-air hoses between the turbo, the intercooler and the throttle body with multi-layer silicone. Each hose carries three to five reinforcement layers depending on inner diameter, holding boost pressure at charge temperatures that swell and eventually blow the original rubber off its clamps. Supplied are the turbo outlet hose, the intercooler inlet hose, the intercooler outlet hose and the throttle body hose.
