The engine air filter sits in the engine bay inside a sealed airbox connected to the intake tubing.

You can access the 2018 Lexus ES 350 engine air filter by opening the hood and locating the rectangular airbox along the intake tract. This is a toolless or basic-hand-tool job on most ES models. If you prefer professional service in Hingham, our team can inspect the housing and seal while replacing the filter to keep intake airflow consistent.

On the 2018 Lexus ES 350, the cabin filter is accessed from the passenger side by removing the glove box or an interior access panel. This placement helps filter pollen and road dust before air reaches the vents. If you schedule with Herb Chambers Lexus of Hingham, we’ll confirm access points and re-seat the filter door to avoid airflow noise or gaps.

• Access: interior trim/panel removal may be required
• Tip: ensure the airflow arrow points in the correct direction
