For the MK3 Focus RS (2016-2018, 2.3L EcoBoost, B58-adjacent tuning headroom), this is the no-nonsense FMIC + hot-side upgrade that actually moves air - not just marketing copy.
Chassis-specific fit: engineered for MK3 Focus RS only - no spacers, no trimming, no ‘works on most’ compromises
100mm GobStopper core: deepest off-the-shelf FMIC for the MK3; proven on stage 2, fast road and track day builds up to 450whp on stock turbos
Included 2.5" alloy hot-side boost pipe: replaces restrictive factory 2.0" piping; compatible with decat, high-flow downpipe and aggressive stage 1 or stage 2 maps
Not an OEM replacement: built for performance - lightweight, pressure-tested, TIG-welded in the UK, finished in Pro-Series Black or Motorsport Silver
Fits with: AIRTEC, Pace, Forge and Pro-Alloy intercoolers - but this kit includes the intercooler and pipe as a matched set
