Engine Air Filter vs Cabin Air Filter

The 2011 Subaru Forester benefits from both an engine air filter and a cabin air filter, each serving distinct purposes that directly affect performance and comfort.

At Mike Shaw Subaru Greeley, our certified technicians inspect both filters during routine service and recommend replacements based on real-world conditions rather than arbitrary time intervals. We use OEM Subaru parts so fit, filtration efficiency, and longevity meet manufacturer standards. Maintaining both filters not only improves immediate drivability and comfort but also prevents downstream maintenance issues, saving you money over time.
