• Panel-style engine air filter with cellulose media
• Phenolic resin-treated media for added durability against moisture ingestion
• 30% more media than OES filters

Detailed Description

Wix WA10961 uses enhanced cellulose filtration media to help maintain airflow while capturing contaminants in demanding daily driving. The polyurethane seal is designed to handle temperature extremes, and the closed-top panel construction supports a secure fit in the airbox. For buyers searching for a Lexus LC500 air filter or Lexus LS500 engine air filter, this part number WA10961 matches the listed applications and includes original equipment part number 1780138060 on select fitments.

WIX Premium Panel Air Filters are positioned for routine service intervals and are engineered for durability in mixed driving conditions. This part cross-references Toyota (e.g., 1780138060) for the same application.

What It Helps Address

• Restricted airflow from a dirty or loaded air filter
• Dust and debris entering the intake system
• Reduced filtration performance during frequent short trips
• Wear from moisture exposure in harsh driving conditions

Installation Notes and Tips

Verify the airbox dimensions and match the panel style, length, width, and height before installation. Confirm fitment for the specific Lexus LC500 or Lexus LS500 application and replace the filter at the manufacturer-recommended service interval. Part number WA10961 should be checked against the vehicle’s existing filter reference before ordering.
