Part #: 800-624
This is a K&N air filter for the valve cover elbow. This breather will fit Datsun 240Z, 260Z, 280Z, and 280ZX, 1970-83. The K&N filter is used as a crankcase vent and takes place of the original Nissan hose that goes from the valve cover to the air filter housing for the carburetors or fuel injection. When converting to aftermarket Weber, Holley, or Mikuni carburetors, this filter will be needed.
