OE 39210-37185 — SENSOR ASSEMBLY-OXYGEN for Hyundai / Kia

KingMay supplies OEM-grade aftermarket parts built to the 39210-37185 factory specification: material grade, dimensional tolerance and surface finish follow the original tooling. They are not dealer-boxed genuine parts, and we quote them that way so there is no ambiguity at customs.

Bulk pricing is tiered: 10 pieces, 50 pieces and full-carton quantities each carry a different unit rate. Piece price also moves with packing format and whether your own brand is printed on the carton, so tell us the landed quantity you are planning.

Stock references leave Guangzhou within 7 working days. If 39210-37185 needs a production run, allow 25-35 days depending on quantity and surface treatment. The schedule is confirmed in writing when the order is placed.

Treat it as a wear item: inspect every 20,000-30,000 km and replace at the first sign of leakage, noise or performance loss. Real service life swings widely with climate, road surface and duty cycle, so mileage on its own is a weak indicator.

A supersession happens when the maker revises a sensor assembly-oxygen 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 39210-37185 we list the current reference; ask our desk for written confirmation before a large order.

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.
