K&N Valve Cover Breather 1970-83 (240Z / 260Z / 280Z / 280ZX)


The breather tube on top of your valve cover was designed to be connected by a hose to the air cleaner to facilitate Positive Crankcase Ventilation (PCV). If you change your carburetor or intake type and no longer have a place for the hose, never block the valve cover vent tube, and don't leave it without the protection of a filter. These filters are a proper fit for the valve cover vent tube, and look great while protecting your engine!
