OE 39210-2B330 — Oxygen sensor assembly for Hyundai / Kia

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.

Aftermarket oxygen sensor assembly comes from tooling houses that hold the original drawings or licensed equivalents. KingMay sources from vetted factories and inspects each batch; the manufacturer name is available on request where your market requires origin documentation.

Standard minimum order is 10 pieces per part number. Mixed orders that combine 39210-2B330 with other electrical & sensors references are welcome — that is how most clients fill an LCL or FCL container without over-stocking a single line.

A supersession happens when the maker revises a oxygen sensor assembly 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 39210-2B330 we list the current reference; ask our desk for written confirmation before a large order.

Watch for noise on cold start, vibration under load, warning lights, fluid seepage or uneven operation. Once any of those appears the oxygen sensor assembly should be inspected, and reference 39210-2B330 replaced if it measures outside specification.

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.
