AIRTEC Motorsport Big Boost Pipe Kit for Ford Focus RS Mk3 2.5 inch
Unlock airflow and power on your Ford Focus RS Mk3 with the AIRTEC Motorsport 2.5 inch Big Boost Pipe Kit. This performance boost pipe upgrade replaces the restrictive 2.0 inch factory boost pipes with freer-flowing 2.5 inch lightweight alloy charge piping for improved response, reduced pressure drop and stronger, more reliable boost on remapped and tuned Focus RS Mk3 models.
Perfect for Stage 1, Stage 2 and high power builds, this hot-side turbo to intercooler pipework is a direct replacement that requires no cutting or modification. We have used this kit on our own cars and customer builds with excellent results and consistent feedback on better throttle response and stronger midrange pull.
