Larger aftermarket intakes on the Mk3 Focus RS create an imbalance with the factory sound suppression chamber resulting in an audible whistle. The COBB Ford Sound Suppression Chamber increases volume over the factory unit which cancels out the resonance to reduce or eliminate the whistle noise. It is compatible with most aftermarket intakes. https://www.cobbtuning.com/products/air-induction/ford-sound-suppression-chamber-focus-rs-2016-2018 | COBB Tuning
