The ETS Front Mount Intercooler, or FMIC, for the Focus RS improves the ability to handle higher airflow and boost while staying cool and not dropping boost pressure. A simple swap out with the stock intercooler makes this job relatively easy and straightforward. The intercooler has a 2.5" inlet and outlet and will hook up to the factory piping for any factory style upgraded intercooler piping. The core measures 26" long x 8.75" tall x 4" thick. This is a much bigger intercooler than stock and will cool down any air your factory Focus RS or upgraded turbo can throw through it.
