It sits in a rectangular airbox in the engine bay, just ahead of the intake tube; the cabin filter is behind the glove box.

The engine airbox opens with clips or screws for easy element access. The glove box typically lowers to reach the cabin filter tray. If you prefer, our Toyota-trained technicians can perform both replacements during a single visit.

• Airbox orientation preserves correct MAF sensor readings
• Cabin filter tray aligns with HVAC airflow direction arrows
• We inspect airbox seals and fasteners at reassembly

The engine air filter cleans intake air for combustion, while the cabin air filter cleans the air your HVAC sends to passengers.

On your V6-powered minivan, the engine filter protects performance and efficiency; the cabin filter protects comfort and health. Both are designed to Toyota specifications for fit and airflow. Replacing each on time helps the Sienna run smoothly and keep the interior pleasant.

• Engine filter: safeguards throttle response and fuel economy
• Cabin filter: reduces dust, pollen, and odors in the cabin
• Different locations, sizes, and media types

Engine filter: reduced power, lower fuel economy, or rough idle; cabin filter: weak HVAC airflow or musty odors.

If your Sienna hesitates on hills or the fan feels weak even on high, the respective filter may be restricted. A quick inspection can confirm condition and restore performance or comfort. Book a checkup with our Auburn service team.

• Look for dark, debris-laden filter media
