OE 39210-23800 — Oxygen sensor assembly for Hyundai / Kia

Wholesale pricing for 39210-23800 depends on order quantity, surface treatment and packing. Standard references are quoted ex-Guangzhou with tiered pricing from 10 pieces upward — send quantity and destination port and a quotation usually returns within one business day.

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 oxygen sensor assembly the practical gap is usually tooling age and packaging rather than fit, provided the tolerance class matches.

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.

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.

For a short distance at reduced load, usually yes — but the risk compounds. A degraded oxygen sensor assembly transfers stress to neighbouring components, so a small repair can grow into a full electrical & sensors rebuild. Book the replacement once the symptom is repeatable.

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.
