Want the ultimate protection for your R600 Cotton Filter? RacingLine’s Cotton Filter ‘Oversock’ simply slides over the top of your R600 Pleated Cotton Filter and protects the surface layer of the cotton from dust and dirt. The Oversock can be cleaned or just replaced to keep your Cotton Filter at its very best for years.

It’s a fact of life that all Cotton Air Filters gradually deteriorate in efficiency as dirt settles on the surface and slowly restricts airflow. RacingLine’s simple oversock helps keeps the surface of the filter clean.

Simply slide it over the top of your Pleated Cotton R600 filter, and the single layer foam material protects debris and dust from settling on the filter’s surface.

Whenever required, simply remove and clean it, or even replace at each service, keeping your R600’s Cotton Filter airflow performing like new.
