Steel Base Vent Breathers |
||||
Steel base crankcase vent filters have vent tubes added to their base. Filters consist of a one piece design with a rubber or chrome top. Filters with mounting studs can be mounted remotely, but require vent hoses and clamps. Filters mounted direct can be pressed into rubber grommets in valve covers. All baseplates are chrome plated. Tubes are zinc. |
