OE 15330-31020 — VVT Solenoid (Oil Control Valve) for Hyundai / Kia

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 engine & fuel system family — always confirm dimensions and connector layout before you swap.

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.

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

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.

Position depends on the platform. On most Hyundai / Kia applications the vvt solenoid (oil control valve) sits on the engine & fuel system assembly and can be reached from the engine bay or the underbody without removing the dashboard. Torque figures and disassembly order are given in the workshop manual for each model.

Stock references leave Guangzhou within 7 working days. If 15330-31020 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.
