Engine Air Filter vs Cabin Air Filter

Understanding the difference between the engine air filter and the cabin air filter helps you protect both vehicle performance and occupant comfort in your 2010 Subaru Legacy. The engine air filter prevents dirt and debris from entering the engine’s intake, preserving horsepower, maintaining fuel efficiency, and protecting sensors and combustion components. A clogged engine filter can cause sluggish acceleration and increased fuel consumption. In contrast, the cabin air filter focuses on the air inside the vehicle, trapping pollen, dust, and particulates to keep the HVAC system working efficiently and passengers breathing cleaner air. Both filters are inexpensive preventive items that pay dividends: replacing them on schedule avoids costly repairs, reduces wear, and improves resale value. At Mike Shaw Subaru, we use OEM parts, provide honest estimates, and our certified technicians complete service quickly so you spend minimal time in our service lounge.
