Wix WP10400 Cabin Air Filter

Cabin Air Filtration for Land Rover

The Wix WP10400 cabin air filter is built to clean the air entering the passenger compartment by capturing pollen, dust, soot, and other airborne contaminants. It uses activated carbon media and Microban antimicrobial technology to help maintain cleaner cabin air in normal and severe driving conditions.

Key Features

• Activated carbon media helps reduce odors from nearby exhaust sources.
• Microban antimicrobial technology inhibits growth on the filter media.
• Panel-style cabin air filter for passenger cars and light trucks.
• Recommended for OEM filter change intervals.
• Fits Land Rover Defender 110, Discovery, Discovery Sport, Range Rover Evoque, and Defender 90 applications.

Detailed Description

Wix WP10400 is a cabin air panel filter designed for Land Rover HVAC systems that use this application. The filter media is intended to remove common airborne contaminants from the air inside the vehicle, while the activated carbon layer adds odor-reducing performance where exhaust smells are a concern. The WP10400 part number is associated with a direct replacement-style service part for routine cabin air maintenance, and the WP10400 reference is useful when matching the correct filter for Land Rover Defender 110, Discovery, Discovery Sport, Range Rover Evoque, and Defender 90 fitments.

What It Helps Address

• Dust and pollen entering the cabin through the HVAC intake.
• Soot and other airborne particles circulating inside the vehicle.
• Odors from traffic and nearby exhaust sources.
• Filter media contamination that can reduce cabin air quality.
• Routine cabin air service needs at the OEM change interval.

Installation Notes and Tips

Verify the vehicle’s cabin air filter location and compare the existing filter dimensions before installation. Confirm fitment by year, make, model, and any notes shown for the application. Replace the filter at the recommended service interval or sooner if airflow drops or odors increase. The WP10400 is listed for multiple Land Rover applications, so matching the exact model year is important.

Quality Assurance

Wix cabin air filters are engineered for passenger car and light truck service and are recommended for OEM filter change intervals. This part cross-references Monroe Shocks & Struts (e.g., 230400, C21776C) for the same application.
