Description
The COBB Sound Suppression Chamber for the 2016–2018 Ford Focus RS is the perfect solution for drivers using larger aftermarket intakes who are tired of hearing high-pitched intake whistle. This direct factory replacement is engineered from high-quality aluminum and finished in sleek anodized black to complement your engine bay.
Aftermarket intakes can throw off the balance of the OEM sound suppression system, causing unwanted resonance and whistling. The COBB chamber increases the internal volume to rebalance airflow acoustics, effectively canceling out the harsh intake noise without affecting performance. Best of all, it installs easily and requires no ECU tuning or calibration. Enjoy your intake’s power — without the noise.
