Detailed Description

Wix WA10946 is an engine air filter designed to maintain clean airflow through the intake system while helping protect the engine from airborne contaminants. Its enhanced cellulose media and panel construction are suited to stop-and-go traffic, dirt roads, construction zones, short trips, and highway driving. For buyers searching for a Lexus LC500h air filter, Lexus LS500h air filter, or Toyota Mirai engine air filter, this part number WA10946 provides a direct replacement option for the listed applications.

The filter uses a closed-top panel design with dimensions of 9.69 inches long, 7.32 inches wide, and 1.929 inches high. Wix recommends this filter for OEM air filter change intervals, and the WA10946 is also referenced by cross numbers such as 97029 and 200946 for the same application.

What It Helps Address

• Restricted airflow caused by a dirty or clogged engine air filter.
• Dust and debris entering the intake system during severe driving conditions.
• Moisture-related media breakdown in demanding weather or road conditions.
• Reduced filtration performance when replacing an aging factory-style filter.

Installation Notes and Quality

Install WA10946 in the factory air filter housing and verify the filter matches the listed dimensions and panel style before installation. Confirm vehicle application by year, make, and model, especially on Lexus LC500h, Lexus LS500h, and Toyota Mirai fitments. Wix positions this filter for OEM service intervals and backs its design with ISO 5011 laboratory testing data.

Wix is known for filtration products used in OE-style service applications, and WA10946 follows that approach with enhanced media, moisture resistance, and a temperature-tolerant seal design where applicable.
