The AIRTEC Motorsport big boost pipe kit is a must for all remapped RS’, everything you need is included in the kit.

Will fit the following intercoolers:

- Direct replacement! No modding required.
Our 2.5″ hard pipe upgrade removes Ford’s 2.0″ restrictive boost pipes. We saw gains of 11.8 bhp & 9 lb/ft torque increase’s over the standard Ford pipes and these gains were achieved by simply bolting on the kit – including the additional cold side pipe.
All pipes have swaged ends to stop the pipes blowing off on BIG BHP Focus RS’.
Fitting takes approx 1 hour.
