Engine Air Filter vs Cabin Air Filter

The engine air filter and cabin air filter serve distinct but equally important roles on a 2012 Toyota Sienna. The engine air filter guards the 3.5L V6 from particles that can erode components and reduce horsepower and fuel efficiency; replacing a clogged engine filter helps maintain the Sienna's towing capacity and response, and protects the engine's longevity. The cabin air filter keeps pollen, dust, and road particulates out of the passenger cabin so HVAC performance stays strong and occupants breathe cleaner air. Both filters should be checked regularly: a clean engine filter preserves power and economy, while a fresh cabin filter improves comfort and reduces allergens. At Larry H. Miller Toyota Murray in Murray, UT, our factory-trained technicians use OEM parts and document service for transparency and warranty protection (repairs covered under warranty must be performed at a certified dealership).
