ZERONINE Design Volume Reduction Chamber – Ford Focus RS Mk3

Description

09 Design Volume Reduction Chamber – Ford Focus RS Mk3

Many Mk3 Focus RS models produce a high-pitched whistle as airflow and power rise. It is most noticeable on cold start and with light throttle. This 09 Design chamber tackles that noise at its source.

The volume reduction chamber replaces the OE turbo resonator. It is engineered to cancel the acoustic frequencies made in the turbo compressor housing. Think of it as noise-cancelling for your turbo. It reduces NVH without restricting airflow, so performance remains unchanged on stock or tuned cars.

Made from durable, heat-resistant materials and designed for the harsh engine bay. It keeps factory-like reliability and does not affect emissions or ECU functions.

• Cuts whistle and drone at idle and cruise
• Keeps boost response and power
• Direct replacement for a tidy install

Good to know

This part reduces unwanted noise, but will not make the car silent. Overall sound depends on your intake, exhaust and tune.
