OE 1121290037 — Air Filter for Volkswagen

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 air filter 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.

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.

Export packing is a neutral carton with inner protection; custom labels, barcodes and box specifications are available for volume orders. Shipments move FOB Guangzhou or Shenzhen, with CIF and DDP terms negotiable.

Three checks: the code printed on your old part must read 1121290037; the number must fall inside the build-year range in the Applications table; and the connector, thread or bolt pattern must match the reference photo. Codes cast into the housing are the most reliable source.

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.
