The AOB Snorkel Sock Pre Filters are designed to be installed on the hood of the snorkel to remove most of the contamination and dirt from the incoming air. They are effective at removing the larger dirt particles and water droplets. As a result, they will greatly reduce the dirt reaching the air cleaner, resulting in extended filter life.

They can be easily installed by simply slipping the "sock" filter over the snorkel head. The filters are fully reusable and just need a good clean to reuse again or replace with new filters.
