DNA replacement air filter "Racing"

Washable and reusable high-performance racing replacement air filter, specially designed for racing use.
Thanks to FCd (Full Contour design) technology, the entire surface of the air filter box inlet is used as a filter medium. This increases the filter area by between 20-80%, increasing the air flow and thus boosting engine performance. The increased air flow also reduces fuel consumption.
The DNA filter medium consists of four layers of special DNA cotton fabric held together by two coated aluminum wire meshes. The special folding technique of the filter medium increases the inner radius of the pleat tips and the resulting areas provide additional filtration.
Care instructions:
The filter should be cleaned and oiled once a year or every 15,000 - 30,000 km. The filter must not be used without oil, as otherwise the filter medium will not provide the optimum filtering effect. Only DNA service products may be used for cleaning and oiling!
