2016 Toyota 4Runner Air Filter

The 2016 Toyota 4Runner engine air filter sits inside the airbox on the driver’s side of the engine bay, just downstream of the intake snorkel.

This location allows quick inspection during routine service in Murray, UT, and helps protect the 4.0L V6 from Wasatch Front dust and road debris. Our technicians access the airbox clips, lift the lid, and verify the seal so unfiltered air can’t bypass the element. If needed, we replace it with a Toyota Genuine filter.

• Driver’s side engine-bay airbox with clip-on lid
• Protects the 4.0L V6 intake tract from dust and debris
• Quick visual check available during a schedule service visit

The engine air filter cleans air entering the 4.0L V6 for combustion, while the cabin air filter cleans air entering the HVAC system for passengers.

On a 2016 Toyota 4Runner, the engine filter protects performance and fuel economy; the cabin filter helps reduce dust, pollen, and odors inside the SUV—useful around Salt Lake City’s seasonal pollen and canyon dust. Both are serviceable items and benefit from OEM media and proper fitment.

• Engine filter: upstream of the throttle body in the airbox
• Cabin filter: behind the glove box within the HVAC inlet
• OEM filters maintain designed airflow and sealing

Common signs include reduced power, poorer fuel economy, or a rougher idle for the engine filter, and weak airflow or musty odors for the cabin filter.

Utah’s dust and winter road grit can load filters faster on a 2016 Toyota 4Runner, especially after off-road use or canyon drives. If you notice sluggish response or stale cabin air, it’s time to inspect. We check media condition, housing seals, and airflow during service.

• Engine: sluggish acceleration, lower MPG, uneven idle
• Cabin: reduced HVAC airflow, haze on vents, odors
• Schedule an inspection online: schedule service

Yes—engine filters are typically DIY-friendly on the 2016 Toyota 4Runner, while cabin filters require glove box access and careful trim handling.

The 2016 Toyota 4Runner cabin air filter is located behind the glove box in the HVAC intake housing.

• Behind glove box; remove damper/stop to access
• Correct orientation ensures proper airflow
• Combine with engine filter check to save a trip

Follow the maintenance interval in your 2016 Toyota 4Runner owner’s manual for the engine air filter.

Because the Wasatch Front can be dusty—especially after off-road use, construction zones, or winter sanding—inspect more frequently and replace as needed. Our technicians in Murray can check restriction, media condition, and sealing during any visit and advise based on your driving mix.

Every 2016 Toyota 4Runner air filter service at Larry H. Miller Toyota Murray follows a consistent, OEM-aligned process.
