2022 Lexus RX 350 Air Filter

The 2022 Lexus RX 350 engine air filter sits inside a rectangular airbox in the engine bay on the intake side of the 3.5L V6.

This top-mounted housing is designed for quick access without removing major components. The cabin air filter, by contrast, is typically positioned behind the glove box. If you’d like a quick check in Grapevine, our Lexus-certified team can confirm condition and fitment during a same-visit inspection.

• Cabin filter: generally behind the glove box
• Quick inspection available during routine visits at Park Place Lexus Grapevine

The engine air filter protects the V6 combustion intake, while the cabin air filter cleans the HVAC air you and your passengers breathe.

On the 2022 Lexus RX 350, the engine filter helps maintain power and fuel efficiency by trapping dust before it reaches the throttle body and MAF sensor. The cabin filter captures pollen and fine particulates that circulate through the climate control system, improving interior air quality in North Texas.

• Engine filter: safeguards performance and MAF/throttle components
• Cabin filter: reduces dust, pollen, and odors in the cabin
• Both are wear items and should be inspected regularly

Common signs include reduced power, lower fuel economy, and rough idle for the engine; weak HVAC airflow and musty odors for the cabin.

If your 2022 Lexus RX 350 feels sluggish or the A/C airflow seems weak, a restricted filter could be the cause. North Texas dust and seasonal pollen can load filters faster, especially on construction-prone routes. Our Grapevine service team can inspect both filters and advise on OEM-spec replacements.

• Engine: hesitation, poor MPG, uneven idle
• Cabin: diminished airflow, increased fogging, odor
• Visual inspection often confirms discoloration/debris

The engine filter is generally DIY-friendly, while the cabin filter may require trim removal; a dealer visit adds OEM-spec parts and intake/MAF checks.
