The engine air filter is located in a rectangular plastic housing on the passenger side of the engine bay, with a large intake hose running to the throttle body.
This article explains where to find the engine air filter, how to access the housing, and how to replace the element on a 2007 ES 350 (2GR-FE).
Location and access
In most ES 350 models from this era, the air box sits on the passenger side of the engine bay near the front. Look for a black plastic rectangular box with a large duct coming from the grille area into its side. The lid is usually secured with clips or small screws, and an intake hose connects the box to the throttle body.
Before beginning any work, ensure the engine is off and cool. Have a clean workspace and good lighting to avoid dropping small parts into the engine bay.
Tools and items you’ll need to replace the engine air filter:
- New engine air filter compatible with the 2GR-FE engine
- Flathead screwdriver or small Phillips screwdriver (for hose clamps or screws)
- Needle-nose pliers (optional, for clip removal)
- Gloves and a clean rag
- Flashlight (optional, for better visibility)
Having the right tools ready helps the replacement go smoothly and reduces the chance of losing small parts.
Step-by-step replacement
Follow these steps to replace the engine air filter in a 2007 Lexus ES 350:
- Park the car on a level surface, turn off the engine, and open the hood. Locate the passenger-side engine air box near the front of the bay.
- Loosen the hose clamp on the intake duct connected to the air box using a screwdriver or pliers.
- Detach the intake hose from the air box and set it aside to expose the air box lid.
- Unclip or unscrew the air box lid to access the filter element inside.
- Remove the old filter and inspect the inside of the box for debris. Wipe the inside clean if needed.
- Install the new filter in the same orientation as the old one (the filter usually has an arrow showing airflow toward the engine).
- Reattach the air box lid and secure the clips or screws. Reconnect the intake hose and tighten the clamp.
- Close the hood and start the engine to verify there are no air leaks and that the engine runs smoothly.
With the new filter properly seated and all connections secured, your ES 350 should intake air cleanly and run efficiently.
Different air filters in the ES 350
Engine air filter vs cabin air filter
The engine air filter discussed here is in the engine bay and protects the engine from dust and debris. The cabin air filter, which cleans the air entering the passenger compartment, is located separately behind the glove box and has its own replacement procedure. Do not confuse the two when planning maintenance.
Summary
In short, the engine air filter on a 2007 Lexus ES 350 lives in a rectangular black air-box on the passenger side of the engine bay, with the intake duct running to the throttle body. Replacing it involves loosening the intake hose, opening the air-box lid, swapping in a new filter (observing orientation), and reassembling. Check your owner's manual for the recommended replacement interval and inspect the filter regularly to decide when a replacement is needed. If you’re unsure, consult a qualified technician for guidance.
