OE 39210-2M410 — Sensor ASSY Oxygen for Hyundai

Incoming batches pass a dimensional check, a material look-up against the electrical & sensors specification, and a visual inspection for finish defects. Critical dimensions are measured per carton and the photographs are archived against the order number.

Build-year coverage is listed row by row in the Applications table above. Where several generations share one number, the newer rows usually carry a revised suffix — compare the last four characters before buying, since a suffix change often means a different connector or bracket.

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 electrical & sensors reference and narrow by build year. Send photos and we will cross-check the number for you.

The Related OE References table above lists the alternates we see most often in trade inquiries. Cross-references work because the engineering envelope is shared across the electrical & sensors family — always confirm dimensions and connector layout before you swap.

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.

Three checks: the code printed on your old part must read 39210-2M410; the number must fall inside the build-year range in the Applications table; and the connector, thread or bolt pattern must match the reference photo. Codes cast into the housing are the most reliable source.
