2012 Toyota 4runner Air Filter in Murray, UT

The 2012 Toyota 4Runner engine air filter sits in a rectangular airbox within the engine bay, ahead of the 4.0L V6 intake tube.

This housing opens to access the pleated filter element that protects the 4.0L V6 from dust common across the Salt Lake Valley. A secure lid and clips keep the seal tight so unfiltered air can’t bypass. If you’re unsure, our Murray service team can confirm placement and fitment quickly.

• Rectangular airbox with clips or screws on top
• Mounted between fresh-air snorkel and intake tube
• Easy visual access during hood-up inspection

The 2012 Toyota 4Runner cabin air filter is located behind the glove box in the HVAC intake.

Lowering or releasing the glove box provides access to the cabin filter tray. This filter screens pollen and road dust that are common around Murray, Millcreek, and Holladay, improving HVAC performance and odor control. If you prefer, our technicians can swap it quickly during your next visit.

• Access panel behind glove box stops
• Slides out on a small filter tray
• No engine-bay access required

The engine air filter protects the 4.0L V6 intake from debris, while the cabin air filter cleans air entering the passenger compartment via the HVAC system.

Both filters matter in Northern Utah: the engine filter safeguards combustion efficiency on canyon climbs, and the cabin filter reduces dust and allergens during inversions and spring blooms. Each uses a different media and sits in a different location, so service needs vary.

• Engine filter: engine bay airbox; performance and fuel economy
• Cabin filter: behind glove box; airflow and odor control
• Different service access and parts

Typical signs include reduced power, lower fuel economy, rough idle (engine filter), weak HVAC airflow, and musty odors (cabin filter).

Dusty construction zones and seasonal pollen around Sandy and West Jordan can load both filters faster. If you notice laggy throttle response or a blower that sounds loud but moves little air, it’s time for an inspection. We can check both filters during any visit.

• Engine: sluggish acceleration or uneven idle
• Cabin: diminished airflow or persistent odors
• Visible dirt or darkened filter media

Yes—the engine filter is DIY-friendly, while the cabin filter typically requires glove box removal and careful reassembly.

Many 4Runner owners comfortably open the engine airbox; the cabin filter involves releasing glove box stops without breaking tabs. Our Murray team adds value with an intake seal check and a quick MAF inspection to ensure smooth running. Choose the route that fits your comfort and time.

• DIY engine filter: basic access and fit check
• Cabin filter: glove box stop release and tray removal
• Dealer adds intake/MAF visual and OEM-spec fit

Yes, a visual MAF sensor and intake housing check is included during air filter service at LHM Toyota Murray.

Next, we check the mass airflow (MAF) sensor area and surrounding ducts for debris or loose connections. If replacement is approved, we install Toyota Genuine engine and/or cabin filters to maintain correct fit and filtration. The glove box is carefully released to access the cabin filter tray, and everything is re-secured to factory feel.

The 2012 Toyota 4Runner uses two distinct filters: an engine air filter that fits the airbox feeding the 4.0L V6 and a cabin air filter that slides into the HVAC intake behind the glove box. Toyota Genuine Parts are engineered for proper sealing and media density, supporting stable airflow and effective particle capture. While actual replacement timing depends on driving conditions (dusty roads, off-road use, and pollen seasons along the Wasatch Front), periodic inspections help prevent performance loss or HVAC odors. During service we also check the intake ducts, airbox clips, and perform a visual MAF inspection for peace of mind. Bring your 2012 Toyota 4Runner to Larry H. Miller Toyota Murray in Murray for OEM-spec filter service — schedule service.
