• Both filters affect comfort and longevity—neglecting either reduces airflow, efficiency, and can increase strain on vehicle systems.
• Our technicians use OEM filters and will explain the benefits and recommended intervals; warranty-covered repairs must be performed at a certified dealership like Park Place Lexus.

What are signs of a bad air filter?

• Reduced acceleration, increased fuel consumption, unusual engine sounds, or musty cabin odor are common signs.
• Visible dirt, darkening, or debris on inspection indicates replacement is needed to protect engine components and cabin air quality.
