Foam filter TwinAir
Over 40 years ago, the sandy, gravelly soils of the Netherlands - and the resulting engine failures - proved that foam and paper filters gave riders airflow but failed to protect them.
Twin Air's breakthrough, combined dual-layer design combines performance and protection.
The fused layers of open-cell foam and fine inner foam trap even the smallest particles.
The new, rounder design increases airflow.
This also applies to the minimized seams, made possible by a revolutionary micro-bonding process: shorter seams = more foam = more flow.
- with flowable, recoil-resistant foam laminated to the inside of the filter
- washable and reusable (40 to 50 times is common)
- two-layer foam (made to specification with cells of equal size and distribution)
- high quality (assembled by hand and checked for perfect fit)
