Engine Air Filter vs Cabin Air Filter

The engine air filter and cabin air filter serve distinct but equally important roles on a 2018 Lexus IS 350. The engine air filter keeps abrasive particles out of the 3.5L V6, protecting fuel injectors, sensors, and internal components to preserve performance, emissions control, and fuel economy. The cabin air filter prevents pollen, dust, and road contaminants from entering the passenger compartment, maintaining a comfortable interior environment and protecting HVAC components. Neglecting either filter can lead to measurable losses: a clogged engine filter reduces horsepower and efficiency while a clogged cabin filter restricts airflow and can strain the AC system. At Stevinson Lexus of Frederick we recommend routine inspections and OEM replacements to maintain factory performance. Our technicians log service and use genuine Lexus parts so your vehicle retains value and warranty coverage. To keep both systems performing, schedule service online or review current offers on our service specials.
