Prok 2 inch air filters have great air-flow but can occasionally pass some water in harsher conditions. Using a Outerwear pre-filter can eliminate this issue. These pre-filters contain uniform micron openings, but they will not constrict air flow. Silicone treatment prevents water from gaining access to the carburetors and the elasticicated opening ensures easy installation and secure fitment to the air filter.

Sold individually.

NOTE: Exact fit for Prok air filter .
