2019 Toyota Sienna Air Filter in Murray, UT

The engine air filter sits inside a sealed airbox in the Sienna’s engine bay, ahead of the intake ducting.

This airbox is typically mounted near the front corner of the bay and opens with clips or screws for quick access. Keeping this filter clean helps the 3.5L V6 maintain smooth airflow and power. If you’re unsure of the exact location, our team at Larry H. Miller Toyota Murray can show you during a visit in Murray.

• Rectangular airbox with clips/screws for tool-light access
• Positioned near the intake snorkel and mass airflow (MAF) sensor
• Designed to protect combustion air for the 3.5L V6

The cabin air filter is located behind the glove box in the 2019 Toyota Sienna.

Access typically involves lowering the glove box and removing a small access panel to reach the filter tray. This filter cleans the air your family breathes by trapping dust and pollen common around the Wasatch Front. If you prefer, our technicians in Murray can replace it during the same visit as your engine filter.

• Access panel behind lowered glove box
• Slide-out tray holds the HVAC cabin filter
• Improves interior air quality and HVAC performance

The engine air filter protects the V6’s intake air for combustion, while the cabin air filter cleans the HVAC air for passengers.

Under the hood, the engine filter safeguards airflow to maintain power and fuel economy. Inside the dash, the cabin filter reduces dust, pollen, and odors in the passenger area. Both matter in Northern Utah’s dusty, high‑pollen seasons.

• Engine filter: located in engine bay airbox
• Cabin filter: located behind the glove box
• Different jobs: performance vs. in-cabin air quality

Common signs include reduced power, lower fuel economy, and a rough idle.

When the 3.5L V6 can’t get enough clean air, drivability suffers—especially on steep grades or freeway merges around Salt Lake City. A quick inspection can confirm if dust buildup from local roads is restricting the filter. We can check it during any visit.

• Sluggish acceleration or hesitant throttle response
• Noticeable drop in MPG
• Dirty or darkened filter media on visual check

Watch for weak HVAC airflow, a musty odor, or increased dust on interior surfaces.

Spring pollen and roadside dust along the Salt Lake Valley can load the cabin filter quickly, affecting comfort and defogging. A fresh filter restores airflow and helps the Sienna’s HVAC work more efficiently. If symptoms persist, schedule an inspection.

• Blower fan sounds normal but airflow feels low
• Persistent odors after starting A/C or heat
• Dust film returning quickly after cleanings

Yes, many owners can DIY the engine and cabin filters, but dealer service includes OEM-spec parts and added inspections.
