The cotton is inserted between two layers of metal mesh which guarantees a long life of the filter allowing to keep its shape unchanged even under high air pressures.

The frame with which the filter is built is in high quality plastic material, this allows to avoid any deformation of the filter inside the air-box.

The result of the special design and high-tech manufacturing is a filter which has a very high flow, low limit, superior dust holding capacity.

Indeed, the efficiency of these filters reaches 98-99%.

The oil used to impregnate the cotton is a very special oil developed by the DNA research department after intensive testing (it is produced by one of the best companies in the sector in the world.)

This particular oil is a very important part of the filter and has the ability to produce a static charge on the cotton and trapping dust particles flowing towards the filter.

The DNA research department is equipped with the most modern Dynojet benches and sophisticated airflow measurement equipment.

Every single filter is tested and verified that it meets DNA's high standards.

The life of the DNA filters is greater than that of the motorcycle, as the cotton with which the filter is built is washable and therefore reusable.

Easy to assemble, as they perfectly replace the original motorcycle filter.
