Nissan RB Series Brass Oil Gallery Plugs | RB26, RB25, RB20

Seal It Right. Prevent Pressure Loss.

When building or rebuilding your Nissan RB engine, don’t overlook your oil gallery plugs. Leaking or missing plugs can cause low oil pressure, oil leaks, or internal failure — especially in high-revving turbocharged RB26, RB25, or RB20 builds.

Note: Price is per pair. Please select the quantity needed when ordering.
