2019 Toyota 4runner Air Filter in Murray, UT

The 2019 Toyota 4Runner’s engine air filter sits in a rectangular airbox in the engine bay on the driver’s side, ahead of the 4.0L V6 intake tube.

This sealed housing feeds clean air to the 270-hp V6, just upstream of the mass air flow (MAF) sensor. In most cases, you’ll see spring clips or screws securing the top cover. Keeping this filter clean helps maintain throttle response and supports the EPA-estimated 17 city/21 highway mpg. Stop by our Murray location for a quick inspection.

• Driver’s-side engine bay, forward of the intake tube
• Inside a black plastic airbox with clips or screws
• Upstream of the MAF sensor to protect the engine

The 2019 Toyota 4Runner’s cabin air filter is behind the glove box, accessed by lowering the glove box and opening a small rectangular HVAC door.

This filter cleans the air your passengers breathe by trapping dust and pollen from the Salt Lake Valley, including Murray, Sandy, and West Jordan. Access typically requires releasing glove box stops and removing a simple cover. If you prefer a pro install, our team in Murray can replace it during the same visit as your engine filter service.

• Located behind the glove box in the HVAC case
• Access via glove box stops and filter door
• Filters dust, pollen, and road debris from outside air

The engine air filter protects the 4.0L V6’s intake from debris, while the cabin air filter cleans HVAC air for passengers.

The engine filter ensures proper airflow to support 270 horsepower and 278 lb-ft of torque, helping maintain fuel economy and drivability. The cabin filter targets interior comfort by reducing dust and odors. Both are important, but they serve different systems and live in different locations on the vehicle.

• Engine filter: performance and engine protection
• Cabin filter: interior air quality and HVAC flow
• Different locations, service steps, and media types

A drop well below the EPA 17 city/21 highway mpg can signal a restricted engine air filter, and weak HVAC airflow or musty odors suggest a dirty cabin filter.

Other engine-related clues include sluggish acceleration, a rough idle, or a dirty filter element in the airbox. On the cabin side, you may notice reduced defrost performance or increased dust on interior surfaces. If you drive Utah’s dusty frontage roads or trailheads, filters can load faster and merit more frequent checks.

• Lower-than-normal fuel economy and throttle response
• Weak HVAC airflow, especially on higher fan speeds
• Musty smells or visible debris on the filter media

Yes—many owners DIY the engine air filter via the airbox clips, while the cabin filter behind the glove box is also accessible with basic steps.

DIY works if you’re comfortable releasing clips, aligning filter media correctly, and reseating housings. At Larry H. Miller Toyota Murray, service includes an intake housing check and a visual MAF inspection to help prevent unmetered air or sealing issues. If you’d like professional help, you can schedule service online.

The official interval is listed in the Toyota owner’s manual and maintenance schedule for the 2019 Toyota 4Runner.

Utah’s dusty construction zones, canyon roads, and unpaved trailheads can load filters sooner than mild, clean conditions. If you routinely drive in Sandy, West Jordan, or up Parleys and Big Cottonwood, ask for more frequent inspections. We’ll check your filter’s condition and advise based on real-world dust and pollen exposure.

• Refer to Toyota’s published maintenance schedule
• Increase inspections for dusty or off-road use
• Quick visual checks available during service

The cabin filter interval is specified in the 2019 Toyota 4Runner owner’s manual and Toyota maintenance guide.

Pollen bursts along the Wasatch Front and winter road grime can saturate the media sooner, especially for drivers in Millcreek, Holladay, and Taylorsville. If airflow weakens or odors develop, replace the filter sooner than the standard interval. We can inspect it during any visit—just mention it when you schedule an appointment.

• Use Toyota’s manual as the baseline interval
• Shorten interval for heavy pollen/dust exposure
• Watch for weak airflow or musty smells

The 2019 Toyota 4Runner uses a panel-style engine air filter housed in a sealed airbox ahead of the intake tract and a rectangular cabin air filter mounted behind the glove box in the HVAC case. Follow the replacement intervals in your Toyota owner’s manual and maintenance guide for both filters. Using OEM-spec media helps maintain the 4.0L V6’s airflow and protect the mass air flow sensor, while a fresh cabin filter supports clear defrosting and interior air quality. Utah dust, winter road sand, and spring pollen can shorten practical service life, so periodic inspections are smart. Bring your 2019 Toyota 4Runner to Larry H. Miller Toyota Murray in Murray for OEM-spec filter service — schedule service.

For the cabin, we lower the glove box, open the HVAC access door, inspect the old filter for excessive dust or odor sources, and install a correctly oriented cabin filter. A visual mass air flow (MAF) sensor check and intake duct inspection help prevent unmetered air leaks. See current service specials and then schedule service online for a convenient visit.
