Engine Piston Ring – Nissan (12033-5RL0A)

Engine Piston Ring contains combustion in the cylinder bore and transfers force to the connecting rod. It is matched by bore diameter and ring groove width rather than by model year alone.

Replace the Engine Piston Ring when compression is low on one cylinder, when oil consumption climbs without an external leak, or when a teardown shows scoring in the bore. Measure the bore before ordering: standard size will not seal a cylinder that needs honing.

Ordering reference for the Engine Piston Ring is part number 12033-5RL0A, categorised under Pistons, Rings & Cylinders. Match that number against the component you are removing before you order.

This is NISSAN dealer-sourced stock rather than an equivalent, so the number on the Engine Piston Ring traces straight back to the manufacturer.
