Engine Air Filter vs Cabin Air Filter

Understanding the difference between the engine air filter and the cabin air filter helps prioritize maintenance for your 2015 Lexus IS 350 C. The engine air filter protects the powertrain — filtering intake air to maintain combustion quality, power (306 hp at 6400 rpm), and fuel economy. A clogged engine filter reduces performance and increases emissions. The cabin air filter, by contrast, cleans the air entering the passenger compartment, improving comfort and health by trapping pollen, dust, and odors. Both filters are small investments that protect larger, more expensive systems and contribute to vehicle longevity. At Stevinson Lexus of Frederick we emphasize preventive care, using OEM parts and factory-trained technicians to ensure proper installation and accurate diagnostics. Scheduling both checks is fast and convenient; schedule appointment online, take advantage of service specials, and ask about service financing to complete the work now and pay over time. Protect performance, comfort, and resale value by letting our team inspect both filters on your vehicle today.
