OE 23412-2G500 — Pin Piston for Hyundai

Start from the code cast or printed on the part you are removing — that is the authoritative source. If it is illegible, use the Applications table on the closest engine & fuel system reference and narrow by build year. Send photos and we will cross-check the number for you.

A supersession happens when the maker revises a pin piston and issues a new tail number. The revision normally changes a small physical detail rather than the fit. Where we know a supersession chain for 23412-2G500 we list the current reference; ask our desk for written confirmation before a large order.

Four variables explain most of the spread: material grade, whether the goods are new production or clearance stock, packing format, and whether the quote is ex-works or landed. Ask for the material certificate alongside the price — that is what makes a comparison like-for-like.

For a short distance at reduced load, usually yes — but the risk compounds. A degraded pin piston transfers stress to neighbouring components, so a small repair can grow into a full engine & fuel system rebuild. Book the replacement once the symptom is repeatable.

Report it with the order number and packing-list line plus photographs. Because every carton is photographed before loading, we can trace the batch immediately and settle the claim against the inspection record instead of arguing from memory.

OEM means the part was produced for the vehicle maker's assembly line; aftermarket means it is made independently to the same engineering drawing. For a pin piston the practical gap is usually tooling age and packaging rather than fit, provided the tolerance class matches.
