OE 39320-3C300 — Sensor Knock RH for Hyundai

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.

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

Match three things: the code on the part you are removing, the build-year range in the Applications table, and the mounting points visible in the reference photo. If all three line up, 39320-3C300 is a confirmed fit. Send your VIN and our export desk will double-check the ambiguous cases.

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.

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.

Wholesale pricing for 39320-3C300 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.
