Engine Air Filter vs Cabin Air Filter

The distinction between the engine air filter and the cabin air filter in a 2021 Nissan Murano is simple but important. The engine air filter protects the 3.5L V6 from particles that would reduce horsepower, foul sensors, or increase wear; a clean engine filter helps preserve the Murano’s 260 horsepower and torque characteristics while optimizing fuel economy. The cabin air filter, by contrast, protects passengers by removing dust, pollen, and pollutants from the air flowing through the HVAC system. Neglecting either unit can lead to immediate comfort or performance issues and higher long-term repair costs. At Larry H. Miller Nissan Mesa in Mesa, AZ, our factory-trained technicians inspect both filters during routine maintenance and recommend OEM replacements matched to Nissan specifications. We document service so your warranty protections remain intact—warranty repairs must be performed at a certified dealership—and offer service financing to get necessary work done now and pay later. To protect engine efficiency and cabin comfort on your 2021 Nissan Murano, schedule service online and review our current service specials for savings.
