- Twin Air brings proven competition technology to consumers with the new Decibel Reducer (DR) foam . With the FIM setting a noise limit of 109dB, manufacturers have had to adapt their engines to comply. Twin Air has also explored solutions to meet this goal while maintaining performance.
- During the 2025 MXGP season, the noise control was already set at 109dB. By working closely with factory teams, Twin Air developed a solution to reduce intake noise. Leveraging their extensive range of foams and expertise, Twin Air created a new type of foam specifically designed to dampen intake noise without compromising airflow or performance.
- Twin Air now offers all types of filters in this material. Just add “DR” at the end of the Twin Air part number.

- width (mm): 165
