RIKEN Japan OEM Piston Ring Set – Honda Civic Integra B16/B18 – STD 81mm – JOPB18STD

Here's a brand new OEM piston ring set from Riken, made in Japan.

Fits Honda Civic and Integra B16 and B18 engines—standard bore size, 81mm.

Manufacturer part number is JOPB18STD, and it's exactly what you'd get if you ordered factory replacements.

Cylinder bore diameter matches at 81mm, and the kit includes all the rings you need for one piston?

Actually, double-check—listing says \Items Included: Piston Rings\ so assume it's a set.

Anyway, these are solid, genuine Japanese parts, not cheap knockoffs.

If you're rebuilding that B-series, these belong in your build.
