Twin Air Pre-oiled motorcycle air filter Kawasaki Kx 450 [450]

• 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 modify their engines to comply. Twin Air has also explored solutions to achieve this goal while maintaining performance.
• During the 2025 MXGP season, the noise control was already set at 109dB. Working closely with factory teams, Twin Air developed a solution to reduce intake noise. By 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" to the end of the part number Twin Air.
