2022 Lexus NX 450h+ Air Filter in Smyrna, GA

The 2022 Lexus NX 450h+ engine air filter sits inside the intake air box in the engine bay.

This sealed housing is typically on one side of the bay, upstream of the mass airflow sensor, protecting the 2.5L inline-4 from debris. During service in Smyrna, our technicians unclip the cover, inspect the element, and check the air box seal for dust intrusion. Keeping this filter clean helps maintain hybrid power and smooth drivability around Atlanta traffic.

• Located in engine bay intake air box
• Upstream of the mass airflow (MAF) sensor
• Protects the 2.5L inline-4 from dirt and debris

The 2022 Lexus NX 450h+ cabin air filter is typically located behind the glove box in the HVAC intake.

This filter screens pollen and road dust before air enters the passenger vents. Access often requires lowering or removing the glove box and sliding out the filter tray. During service, we also inspect the cowl intake area for leaf buildup that can restrict airflow and cause odors.

• Behind glove box in HVAC intake path
• Requires glove box removal/lowering for access
• Screens pollen, dust, and fine particulates

The engine air filter protects the engine’s intake, while the cabin air filter cleans the air entering the passenger HVAC system.

On the 2022 Lexus NX 450h+, the engine element sits in the under‑hood air box feeding the 2.5L inline‑4, and the cabin element sits behind the glove box. Both are serviceable items with different materials and airflow paths. We replace them with Lexus Genuine Parts to match OEM filtration and fit.

• Engine filter = combustion air; cabin filter = passenger air
• Different locations and service procedures
• Use Lexus Genuine Parts for correct fit and filtration

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

If your NX 450h+ feels sluggish or the HVAC struggles to move air, the filters may be restricted. In our Smyrna shop we inspect the intake box, MAF area, and cabin filter tray to confirm the cause and replace only what’s needed. Timely service helps maintain performance and clean cabin air.

• Engine: hesitation, decreased MPG, uneven idle
• Cabin: weak vents, odor, increased fan noise
• Visual: darkened, debris‑laden filter media

The engine filter is generally DIY‑friendly, while the cabin filter often needs glove box removal that some owners prefer a dealer to handle.

Many NX 450h+ owners can unclip the air box and swap the engine filter with basic tools. The cabin filter involves trim movement and careful seating of the element to avoid airflow noise. Dealer service adds an intake/MAF visual check and Lexus‑spec parts. You can schedule service online if you’d like us to do both.

• Engine filter: simple clips and housing cover
• Cabin filter: glove box lowering and tray access
• Dealer adds intake and MAF inspections

Our air filter service for the 2022 Lexus NX 450h+ focuses on OEM‑spec performance and clean cabin air. We begin with an under‑hood inspection, opening the intake air box to check the engine filter’s media and seals. If replacement is needed, we install a Lexus Genuine engine filter and reseat the housing to prevent unmetered air leaks. Next, we access the cabin filter behind the glove box, inspect the tray, and replace the element if it’s dirty or odorous.

We also perform a quick visual of the mass airflow (MAF) area and look for debris around the cowl intake that can restrict HVAC flow. Disposal of old filters is handled responsibly. If you’re planning other maintenance, ask our team to coordinate services in one visit. Ready to proceed? Review service specials and schedule service online.
