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 cooling system family — always confirm dimensions and connector layout before you swap.

Report it with the order number and packing-list line plus photographs. Because every carton is photographed before loading, we can trace the batch immediately and settle the claim against the inspection record instead of arguing from memory.

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 radiator air duct the practical gap is usually tooling age and packaging rather than fit, provided the tolerance class matches.

Wholesale pricing for 51748069176 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.

Aftermarket radiator air duct 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.

For a short distance at reduced load, usually yes — but the risk compounds. A degraded radiator air duct transfers stress to neighbouring components, so a small repair can grow into a full cooling system rebuild. Book the replacement once the symptom is repeatable.
