Engine Air Filter vs Cabin Air Filter
The 2018 Lexus RX 350L relies on two distinct filtration systems: the engine air filter and the cabin air filter. The engine filter keeps contaminants out of the combustion system, protecting injectors, sensors, and cylinders; maintaining it preserves horsepower, lowers emissions, and reduces fuel consumption. The cabin filter improves passenger comfort by removing pollen, dust, and exhaust particulates from incoming ventilation air. At Park Place Lexus Grapevine in Grapevine, TX, our certified Lexus technicians inspect both filters during routine service and explain the condition in clear terms. We use genuine Lexus parts to ensure proper fit and long service life, and our transparent pricing highlights immediate savings from correct replacement and long-term savings from optimized fuel economy and fewer downstream repairs.
