K&N Engineering knn85-1450

The K&N marine-style vent hose adapter mounts between the top and bottom plates of a custom chrome air filter assembly to accommodate breather hoses without drilling into the filter base. Available in sizes from roughly 2-3/4 to 6 inches, this adapter lets you route vent hoses cleanly while preserving the filter housing. It is intended for marine or custom air cleaner setups.
