Engine Air Filter vs Cabin Air Filter

The 2021 Lexus NX 300 requires attention to both its engine air filter and cabin air filter to deliver the refined performance and comfort Lexus owners expect. The engine air filter preserves intake airflow and protects the turbocharged 2.0L inline-4 from contaminants — critical for maintaining the vehicle’s 235 horsepower and 258 lb-ft of torque. The cabin air filter ensures clean, allergen-free air inside the vehicle, improving occupant comfort and HVAC efficiency. At Stevinson Lexus of Frederick in Colorado, our certified technicians examine both filters during routine maintenance, using OEM parts to ensure fit and filtration that meet Lexus standards. Choosing dealership service provides immediate benefits — accurate diagnostics, proper installation, and warranty protection — and long-term savings from avoided engine wear and improved resale value.
