Nissan OEM Rear Valve Cover "Half Moon" Plugs - RB20 RB25 RB26
These are not included in any of the gasket kits on the market. These are made of rubber and they tend to dry up and leak as they're wedged in the back on the cylinder head next to the firewall. Both in close proximity to hot exhaust components. These half moon grommets sit between the valve cover gasket and the cylinder head, completing your valve cover installation.
Includes 2 plugs (one for each came side).
