Ford Focus ST Sound Symposer Delete - COBB - Stealth Black - 2013-2018. This piece removes the factory symposer assembly to deliver a cleaner engine bay and a more natural soundtrack without the piped-in drone.

Designed by COBB for proper fitment on the Focus ST, this delete replaces the plastic device that routes intake pulses into the cabin. By closing that path, it removes an extra junction in the charge system, helps minimize potential leak points, and calms cabin resonance on longer drives. The stealth black finish keeps it low-key under the hood, and the straightforward, reversible install uses factory connection points with common hand tools.
