2021 Toyota Highlander Air Filter in Murray, UT

The 2021 Toyota Highlander engine air filter sits in a rectangular airbox inside the engine bay, typically on the driver side near the intake tube.

Pop the hood and look for the plastic airbox connected to the intake snorkel on your 3.5L V6. Releasing a few clips or screws lets you lift the lid and access the filter. If you’re unsure, our technicians in Murray can confirm placement and fitment during a quick inspection.

• Engine: 3.5L V6 (6VNAG3.5), naturally aspirated
• Access via airbox clips/screws; no special tools usually required
• We inspect the intake tube and MAF housing during service

The 2021 Toyota Highlander cabin air filter is located behind the glove box inside the HVAC intake housing.

Open the glove box, release its side stops, and lower it to expose the rectangular HVAC access panel. Removing the cover reveals the cabin filter tray for a quick swap. If you prefer, our Murray service team can replace it and reset your maintenance reminders during the visit.

• We dispose of the old filter and install an OEM-spec unit

The engine air filter protects the 3.5L V6 intake, while the cabin air filter cleans the air entering the passenger compartment HVAC.

The engine filter supports combustion and helps maintain power and fuel economy by keeping debris out of the throttle body and MAF. The cabin filter captures dust and allergens for cleaner breathing and better defrost performance. Both are easy to inspect and are serviced routinely in Murray.

• Engine filter: in-bay airbox feeding the intake
• Cabin filter: behind glove box, filters HVAC airflow
• Both replaced with Toyota OEM-spec elements

Common signs include reduced power, poorer fuel economy, and rough idle (engine), plus weak HVAC airflow and musty odors (cabin).

Dust from Wasatch Front driving and spring pollen can load filters quickly. If your Highlander feels sluggish or your vents blow weaker air, it’s time to inspect both filters. Our team in Murray can check engine and cabin elements and advise on OEM replacements.

• Engine: hesitation, louder intake noise, lower MPG
• Cabin: reduced airflow, window fogging, odors
• Visual check: dark, debris-laden pleats indicate replacement

Yes, many owners can DIY the engine and cabin filters, but dealer service adds an intake/MAF inspection and confirmation of OEM-spec fit.

Your 2021 Toyota Highlander benefits from a methodical service that protects both performance and in-cabin comfort. We begin with an engine airbox inspection, checking clips, seals, and the intake snorkel for cracks or debris. The engine air filter is removed, its pleats are evaluated for dust loading, and an OEM-spec element is installed with the correct orientation. Next, we access the cabin filter behind the glove box, slide out the tray, and install a Toyota-spec cartridge to restore HVAC airflow and reduce allergens. A visual inspection of the mass airflow (MAF) sensor and intake tract helps prevent drivability issues. We finish by resetting maintenance notes, disposing of the old filters responsibly, and reviewing any findings. Ready to book? View service specials and schedule service online.

The 2021 Toyota Highlander uses two filtration elements: an engine air filter in the underhood airbox and a cabin air filter behind the glove box. The powertrain is a 3.5L V6 (engine code 6VNAG3.5), naturally aspirated, with 295 horsepower and a mass airflow sensor that relies on a clean, well-sealed filter to report accurate intake readings. The cabin filter supports HVAC efficiency, defogging, and odor control by trapping dust and pollen common along the Wasatch Front.
