Engine Piston Ring – Nissan (12033-9BF0A)

Engine Piston Ring is a reciprocating component that seals the combustion chamber. Clearance and surface finish decide whether it seals correctly, so the bore has to be measured before a replacement is chosen.

Replace the Engine Piston Ring when a leak-down test shows air escaping past the rings, when the skirt is scuffed, or when ring lands are cracked. Check the ring end gap in the bore it will run in.

This Engine Piston Ring is listed as part 12033-9BF0A (Pistons, Rings & Cylinders). Where a number has been superseded, the current reference is the one that ships, so check any supersession note before ordering.

This is genuine NISSAN stock, supplied for the Engine Piston Ring with the manufacturer number intact so the reference on the box matches the catalogue.
