Two oil filter part numbers apply to the 2003 Highlander, depending on which engine it uses. The short answer is: 04152-YZZA1 for the 2.4L four-cylinder, and 90915-YZZD for the 3.0L V6. Confirm your engine to choose the correct one.
Engine Options in the 2003 Highlander
In 2003, the Highlander was offered with two powertrains. The four-cylinder 2AZ-FE and the 3.0-liter V6 1MZ-FE each require a different oil filter. Using the wrong filter can compromise seal integrity and filtration performance.
For quick reference, here are the official Toyota oil filter numbers by engine:
- 2.4L inline-4 (2AZ-FE) — OEM oil filter part number: 04152-YZZA1.
- 3.0L V6 (1MZ-FE) — OEM oil filter part number: 90915-YZZD.
The exact catalog listing can vary by production batch or region, so it’s best to verify with the official Toyota parts catalog for your VIN. If shopping aftermarket, use the OEM number to cross-reference in your preferred supplier’s catalog.
How to confirm your Highlander’s engine
To ensure you order the correct filter, verify the engine code. Look for the engine code stamped on the engine block or on a tag/sticker under the hood, or pull the data from the vehicle’s VIN. If you’re unsure, check your owner's manual or service records to determine whether your Highlander uses the 2AZ-FE or the 1MZ-FE.
Getting It Right: Practical Tips
When replacing the filter, also follow the service manual’s guidance on oil type and capacity, gasket/seal replacements, and torque specifications for the drain plug. Using the correct filter number helps ensure proper fitment and filtration performance over the service interval.
Summary
For the 2003 Toyota Highlander, oil filter numbers depend on the engine. The 2.4L 2AZ-FE uses 04152-YZZA1, while the 3.0L 1MZ-FE uses 90915-YZZD. Always verify with the vehicle’s VIN and the official Toyota parts catalog to confirm the exact match, and follow manufacturer guidance for oil type and change intervals.
