Detailed Product Description

WIX 42476 is engineered as an OE-style engine air filter for Toyota 4Runner, Lexus GX470, Lexus LX470, and Toyota Land Cruiser fitments. The filter uses more media than many original-equipment service filters and is built to support consistent airflow while helping protect the engine from dust and debris. Laboratory testing referenced to ISO 5011 shows at least 99.5% efficiency based on Wix 42389 testing data.

This part cross-references NAPA Gold Filters 2476 and FRAM CA8918 for the same application. The WIX 42476 is a practical choice for routine air filter service where correct fit, filtration efficiency, and moisture resistance matter.

Common Problems This Filter Helps Address

• Restricted airflow from a dirty or clogged intake filter
• Dust and road debris entering the engine intake
• Reduced filtration performance in stop-and-go or dusty driving
• Moisture-related filter deterioration
• Service intervals missed on Toyota and Lexus air intake systems

Installation Notes and Tips

Install the filter in the factory airbox and confirm the seal seats evenly around the perimeter before closing the housing. Replace the filter at the manufacturer-recommended service interval, or sooner if the vehicle is driven on dirt roads, construction routes, or in heavy traffic. Verify fitment against the vehicle’s existing filter dimensions before installation.

Quality Assurance

WIX designs this filter for normal and severe driving conditions and recommends it for OEM air filter change intervals. The phenolic resin-treated media and high-tear-strength polyurethane seal are used to support durability across hot and cold temperature swings.
