Twin Air Air Filter Oiled (Noise Reducing) KTM SX/F 125/150/250/300/350/450 2026

Twin Air brings race-proven technology to consumers with its new Decibel Reducer (DR) foam. With the FIM's introduction of the 109 dB noise limit, manufacturers have had to adapt their motorcycles to comply. Twin Air has also explored solutions to meet this standard while maintaining performance.

During the 2025 MXGP season, the noise reduction was already set at 109 dB. In close collaboration with factory teams, we developed a solution to reduce intake noise. By leveraging our extensive foam range and expertise, Twin Air has developed a new type of foam specifically designed to dampen intake noise without compromising airflow or performance.

In the 2026 KTM 125SX, 250SXF and 350SXF models you will already find this new foam in the EU versions (part number: 154119DR / 154119DRX), offering riders the perfect combination of noise reduction and race-ready performance.
You can now buy any type of filter in this material. Simply add "DR" to the end of the part number.
