2022 Lexus RX 350 Air Filter in Hingham, MA

The engine air filter sits inside the sealed airbox in the engine bay, upstream of the intake to the 3.5L V6.

This airbox is typically mounted near the front corner of the bay and secured with clips or screws for tool-free or simple access. On the 2022 Lexus RX 350, the filter protects the 3.5-liter V6 intake from dust and debris common on New England roads. Replacing it helps maintain smooth airflow and consistent performance.

• Located in the engine bay airbox before the intake tube
• Access usually via clips/screws on the airbox lid
• Protects the 3.5L V6 from dust, sand, and road debris

The cabin air filter is typically located behind the glove box in the HVAC intake path.

For the 2022 Lexus RX 350, you usually lower or remove the glove box to access a trim panel that covers the filter slot. This filter cleans air entering the cabin, capturing pollen and fine particles that are common during Massachusetts allergy seasons. If you prefer, our team can replace it during the same visit as your engine filter.

• Behind the glove box on most RX 350 models
• Access via removable trim cover over the HVAC intake
• Keeps cabin air cleaner for passengers

The engine air filter protects the 3.5L V6’s intake air, while the cabin air filter cleans the HVAC air you breathe inside the RX 350.

These filters do different jobs in different locations. The engine air filter supports performance and fuel efficiency; the cabin air filter improves in-cabin air quality and HVAC airflow. Replacing both on schedule helps your RX 350 run smoothly and keeps the interior comfortable for daily driving in and around Hingham.

• Engine filter: combustion air, lives in engine bay airbox
• Cabin filter: passenger air, lives behind glove box
• Both are serviceable and typically replaced without major disassembly

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

On the 2022 Lexus RX 350, a dirty engine filter can restrict the 3.5L V6’s airflow, making acceleration feel lazy. A clogged cabin filter can lower fan output and allow odors to linger. If you notice these symptoms on local routes through Hingham or Quincy, it may be time to replace one or both filters.

• Engine: sluggish acceleration, reduced fuel economy
• Engine: possible rough idle or intake noise
• Cabin: weak airflow, dusty smell, increased window fogging

Yes—many owners DIY the engine filter; the cabin filter is also doable but may require glove box removal and careful trim handling.

DIY engine filter swaps are straightforward on the 2022 Lexus RX 350 if you’re comfortable opening the airbox. The cabin filter sits behind the glove box, which may involve clips and tabs. Dealer service adds OEM-spec parts, intake/MAF checks, and proper disposal. If you prefer a hands-off visit, schedule service with Herb Chambers Lexus of Hingham.

Open the airbox, remove the filter, and inspect the pleats against light—replace if the media is dark or clogged.

On the 2022 Lexus RX 350, release the airbox clips or screws and lift the cover enough to slide the filter out. Hold it up to a light source; if you can’t see light through multiple pleats, it’s time to replace it. Re-seat the gasket evenly and close the airbox securely to prevent unmetered air.

• Release airbox clips/screws and lift the lid
• Check pleats for light transmission and debris
• Ensure proper gasket seating when reinstalling

Follow the interval listed in your 2022 Lexus RX 350 maintenance schedule in the owner’s manual.

Driving conditions in Massachusetts—stop-and-go traffic, construction dust, and pollen—can shorten real-world intervals. If you notice weak airflow or odors, replace sooner. Our team can inspect both filters during any visit and advise based on condition; book a checkup via schedule service.

• Use the owner’s manual maintenance chart

We follow a clear, repeatable process for the 2022 Lexus RX 350 to keep both the engine and cabin breathing cleanly. First, a visual inspection confirms the current condition of the engine air filter and the integrity of the airbox lid, clips, and gasket. Next, we check the cabin air filter behind the glove box and assess airflow through the HVAC intake. If replacement is needed, we install OEM-spec filters and ensure proper orientation and sealing. A quick intake housing check and a visual look at the MAF sensor help confirm there are no leaks or contamination that could skew readings. We dispose of old filters responsibly, reset reminders if applicable, and note findings on your repair order. Ready to plan your visit? Use our online tool to schedule service.

The 2022 Lexus RX 350 uses two primary filters: an engine air filter for the 3.5-liter V6 intake (3.5L, V-type, premium unleaded recommended) and a cabin air filter that screens HVAC air for passengers. OEM-spec filters provide the correct media density, pleat geometry, and sealing surfaces for the RX 350’s airbox and HVAC slot. Replace filters per the service schedule in your owner’s manual, and consider earlier replacement if airflow or air quality declines. Keeping the engine filter fresh supports smooth power delivery from the 295-hp V6, while a clean cabin filter maintains strong defrost and A/C performance.
