Step-by-Step Guide to Changing the Air Filter

  1. Locate the air filter housing: Open the hood and find the air filter box, usually a black plastic box near the engine.
  2. Remove the housing cover: Use a screwdriver or socket wrench to undo screws or clips holding the cover in place.
  3. Take out the old air filter: Carefully lift out the used air filter and inspect the housing for dirt or debris. Wipe it clean with a cloth if necessary.
  4. Insert the new air filter: Place the new filter in the housing with the rubber seal facing up or as specified in your owner's manual.
  5. Reattach the housing cover: Secure the cover back with screws or clips, ensuring a tight fit to avoid air leaks.
  6. Close the hood: Double-check your work and close the hood securely.

Changing your Lexus GS 350’s air filter every 15,000 to 30,000 miles, or more often in dusty conditions, can maintain engine efficiency and extend its life. Always consult your owner's manual for specific recommendations.
