Replacing the factory plastic tubing with 2.5″ mandrel bent piping, the COBB Focus RS Hard Pipe Kit removes restriction and improves airflow to the engine of your Focus RS. This kit consists of single piece pipes made from mandrel bent aluminum tubing on both the cold side and hot side of the intercooler. The results are weld-free pipes from the turbo outlet to intercooler inlet and from the intercooler outlet to the throttle body. COBB 4-ply silicone hose couplings and heavy duty T-Bolt hose clamps finish off this kit and ensure the pipes stay put.
