DNA Air Filter for BMW R18 Series (2020-25)

DNA Air Filter for BMW R18 Series (2020-25)

The DNA Air Filter for BMW R18 Series (2020-25) provides a high-flow replacement designed for Road use. DNA developed these filters to work with the existing factory air box while increasing airflow and maintaining excellent filtration.

The filter features DNA’s advanced FCd (Full Contour design). This design allows the filtering material to follow the air box contour and use the available surface as an active filtering area. As a result, the filter supports efficient airflow while maintaining strong filtration performance. Visit our website for more products Dirt Street.

Advanced FCd Full Contour Design

The DNA Air Filter uses DNA’s advanced FCd design. The filtering material follows the shape of the air box, helping make effective use of the available filtering surface.

Moreover, the FCd design helps reduce dead spots that can create turbulence. This approach supports the filter’s high-flow characteristics while maintaining its filtration efficiency.

22.35% Increased Airflow

The DNA filter set provides a 22.35% increase in airflow compared with the BMW stock filters.

The DNA filters deliver 124.30 CFM, while the BMW stock filters deliver 101.60 CFM under the specified test conditions. Therefore, the DNA setup provides substantially higher airflow than the standard filters.

DNA designed its replacement air filters to increase horsepower and acceleration while providing excellent filtration.

98%-99% Filtration Efficiency

The DNA Air Filter for BMW R18 Series (2020-25) provides 98%-99% filtration efficiency. DNA achieves this level using four layers of DNA cotton.

The supplied information also lists the filtration efficiency as ISO 5011 tested. This high filtration level works alongside the increased airflow to provide a balanced high-flow replacement for the factory filters.

Easy Installation

Installing the DNA filters is straightforward. Riders can follow the installation instructions included in the BMW workshop manual.

Furthermore, the filters use a drop-in design for the existing factory air box. Therefore, riders can replace the original filters without changing the air box.

Washable and Reusable Design

DNA replacement air filters feature a washable and reusable design. This provides a practical alternative to conventional disposable filters.

In addition, the custom-fit construction allows the filters to work with the existing factory air box. Their drop-in design keeps installation simple while adding high-flow filtration.

Designed for Road Use

The DNA Air Filter for BMW R18 Series (2020-25) is designed specifically for Road use.

The combination of increased airflow, high filtration efficiency and reusable construction makes these filters a practical high-flow replacement for riders who want to improve the air intake system while retaining the factory air box.
