OEM part number and fitment

What to know about the official part

For the 2004 RX330, the official Toyota/Lexus intake air filter most commonly recommended is 17801-21060. This OEM part is designed to fit the stock air box and ductwork. If a vendor lists a different number, it may reflect regional variations or supplier coding; always cross-check with a VIN-based lookup or by consulting a Lexus dealer to confirm exact fitment.

Before you shop, use the following steps to verify the correct part number for your exact vehicle:

• Inspect the air filter housing for any stamped part numbers or labels that match 17801-21060 or show a close variant.


• Consult the vehicle’s owner’s manual or the official service/parts catalog for the recommended replacement part.


• Enter your VIN into the official Toyota/Lexus parts lookup or a trusted retailer’s site to confirm the exact fit for your car.


• Contact a Lexus dealership or qualified mechanic with your VIN and engine code (3MZ-FE for the RX330) to verify the correct part number.

Concluding note: These verification steps help ensure you order the correct air filter for your specific RX330 model year and market, reducing the risk of fitment issues.

Alternatives and cross-reference tips

If the OEM part is temporarily unavailable, you can consider reputable aftermarket filters that are clearly labeled as compatible with the RX330’s 3.3L engine and air box interface. When using non-OEM filters, confirm filter size, gasket seal, and compatibility with the mass airflow sensor housing, and always verify the exact part via VIN and engine code before purchasing.

• Choose aftermarket filters that explicitly list compatibility with the RX330 or 3MZ-FE engine and 17801-21060 equivalence.


• Use vehicle-specific cross-reference tools or dealer-supported catalogs to compare OEM vs. aftermarket options for your VIN.


• Check return policies and warranty in case the fit isn’t perfect after installation.

Bottom line: VIN-based verification remains the most reliable method to ensure you’re ordering the correct air filter, whether you choose OEM or aftermarket parts.

Summary

The 2004 Lexus RX330 typically uses the OEM air filter part number 17801-21060.
