BOXER Engine Oil Filter

The Subaru oil filter complete (part number 15208AA15A) is a genuine Subaru direct replacement oil filter engineered to maintain the cleanliness of your SUBARU BOXER® engine's oil. Its design includes a spring-loaded relief valve to ensure consistent oil flow, even during cold engine starts. The pleated filter media is constructed to effectively capture contaminants and provide reliable filtration throughout the recommended oil change intervals. This oil filter is specifically designed with a bottom assembly that helps prevent leaks, a critical feature for Subaru vehicles. By removing dirt, debris, and impurities from the circulating oil, it plays a vital role in protecting the engine's internal components from wear and tear. Regular replacement of the oil filter, alongside routine oil changes, is essential for maximizing engine life and maintaining optimal fuel economy. This part fits various Subaru models, including the Ascent (2019-2021), Crosstrek (2022-2025), Forester (2022-2025), Impreza (2017-2021), Legacy (2013-2021), and Outback (2013-2021). It is specifically noted to be for 2.5L engine applications and does not fit the 3.6L 6-cylinder engine. The part number 15208AA15A has been superseded by 15208AA21A, though either filter is generally considered compatible.
