2018 Lexus NX 300 Air Filter in Grapevine, TX

The 2018 Lexus NX 300 engine air filter sits in a rectangular airbox inside the engine bay, ahead of the turbocharged 2.0L inline-4 intake.

Lift the hood and look for the closed plastic airbox connected to the intake ducting; the filter is inside that housing. Keeping this filter clean helps your 235-hp turbo engine breathe efficiently and protect the mass airflow sensor. Our Grapevine team can inspect and replace it using OEM-spec media.

• Located in engine bay airbox near front corner
• Protects turbocharged 2.0L intake from dust and debris
• Accessed by releasing airbox clips/screws

The 2018 Lexus NX 300 cabin air filter is located behind the glove box within the HVAC intake housing.

Open the glove box and remove the inner stop tabs or panel to access the filter tray. This filter screens pollen and fine dust—useful during North Texas allergy seasons and windy days around Dallas–Fort Worth. Our service team in Grapevine can replace it and confirm proper HVAC airflow.

• Captures pollen, dust, and odors for the cabin
• Requires glove box removal to access tray

The engine air filter protects the 2.0L turbo intake for combustion, while the cabin air filter cleans air entering the passenger HVAC system.

Engine filters focus on safeguarding performance, fuel metering, and the turbo/MAF from debris. Cabin filters target occupant comfort by trapping dust, pollen, and particulates common in North Texas. Both are important but serve different systems in your 2018 Lexus NX 300.

• Engine: intake protection and airflow to turbo
• Cabin: HVAC air quality for occupants

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

If you experience these symptoms, a quick inspection at Park Place Lexus Grapevine can confirm the cause.

• Engine: sluggish acceleration or uneven idle
• Fuel economy drop over recent tanks
• Cabin: reduced fan output or odor on startup

Yes—many owners DIY the engine filter, while the cabin filter often requires glove box removal and precise reassembly.
