The engine air filter protects the 338-hp V6 from dust that could affect the MAF sensor and fuel economy, while the cabin microfilter traps pollen and road debris entering the interior vents. Around Atlanta and Marietta, seasonal pollen makes the cabin filter especially important for comfort and clarity of airflow.

• Cabin filter: in HVAC path to reduce pollen/odors
• Both are replaceable service items on the GS 450h

Common signs include reduced power, lower MPG, rough idle (engine), and weak airflow or musty odors (cabin).

In the 2016 Lexus GS 450h, a restricted engine filter can impact intake flow to the 3.5L V6, while a dirty cabin filter can limit HVAC output and introduce smells. Metro Atlanta dust and pollen can accelerate debris buildup. If you notice these symptoms, book a quick check and replacement.
