BMC Air Filters
High performance drop-in replacements for the factory air filters; fit OEM Mercedes-Benz airboxes for improved airflow and performance.
Starting with its outer frame, BMC uses a special soft rubber material made in a process called "full molding", which not only provides a much tighter seal around the filter, but also eliminates any potential cracking or breaking of the filter. The filter element itself is made of a washable cotton material that provides nearly 40% greater airflow than paper, enclosed in an alloy mesh screen which helps the filter keep its shape and protects against larger debris and dirt. The increased flow of air through the filter provides a steady stream of clean air to the engine, resulting in much more consistent and efficient power.
