do88 replaces the ageing OEM rubber charge air hoses on the Focus RS MkII with a three piece silicone set, built with three to five reinforcement plies depending on hose diameter so the hoses hold boost pressure and heat without the cracking the original rubber develops with age. This version carries the connection for the factory symposer, so it suits cars that still run one. The kit covers the turbo outlet hose, the intercooler outlet hose and the throttle body hose. Hose clamps are sold separately.
