There isn’t a single universal air-filter part number for the 2021 Highlander. The correct engine air-filter part number depends on which engine the vehicle uses and the market it’s sold in. For the exact number, consult Toyota’s official parts catalog or your local dealer with your VIN.
Understanding how the part numbers are determined
The 2021 Highlander lineup includes different powertrains across regions, which means separate engine air-filter part numbers can apply to each configuration. The most reliable way to confirm the correct number is to reference official Toyota diagrams or speak with a dealer using your VIN and market specification.
- Gasoline-powered Highlander (non-hybrid) configurations: The engine air-filter part number varies by market and year model; consult the Toyota Parts Catalog for your region and VIN to identify the exact number.
- Hybrid Highlander configurations: Hybrid models may use a different engine air-filter part number from the gasoline-only models; verify via the official parts catalog or dealer using your VIN.
In practice, verifying the exact part number with an official source eliminates ambiguity due to regional and drivetrain variations.
How to locate the exact part number for your Highlander

These steps help ensure you obtain the correct air filter for your specific 2021 Highlander configuration, avoiding mismatches from regional or drivetrain differences.
