Why This Filter Matters

The Wix 46109 helps keep dust and debris out of the engine intake stream while maintaining the airflow needed for normal operation. It is a practical choice for Toyota Tacoma and 4Runner service, as well as Lexus SC300, SC400, and Toyota Supra maintenance where a direct-fit panel air filter is required.

• Reduced engine air contamination from road dust and airborne debris
• Restricted airflow caused by a loaded or dirty air filter
• Premature intake wear from inadequate filtration
• Moisture-related filter breakdown in changing weather conditions
• Service issues tied to overdue OEM air filter replacement intervals

Installation Notes

Replace the filter at the manufacturer-recommended service interval or sooner if the vehicle is driven in stop-and-go traffic, on dirt roads, near construction sites, or on short-trip routes. Verify the airbox is clean before installing the new panel filter, and confirm the filter seats evenly in the housing before closing the lid.
