OE 18843-10063 — Spark plug for Hyundai / Kia

Stock references leave Guangzhou within 7 working days. If 18843-10063 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.

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

Every shipment of 18843-10063 leaves with a packing list, photo documentation and a QC report. Warranty terms are agreed per contract and reference that inspection record; claims are settled in writing against the documentation.

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.

Aftermarket spark plug 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.

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 body & interior family — always confirm dimensions and connector layout before you swap.
