The Airtec 70mm Cold Side Boost Pipe has been developed for the Ford Focus MK2 RS and provides significantly better airflow compared to standard lines. The hose starts with a 63mm connection, so it fits directly on the original intercooler and most aftermarket intercoolers. It then extends to 70mm, which ensures a faster and freer airflow to the throttle valve. This is a direct replacement without modifications and at the same time a Symposer Delete.
