15208AA21A Oil Filters for Subaru Models - 6 Pack Kefly

Our review of the 15208AA21A oil filter (6 pack) finds it best suited for Subaru owners who want a direct-fit replacement that covers a wide range of model years. This review is written from hands-on comparison with OEM fit guidelines and the product description: the filter's biggest selling point is compatibility across many Subaru 4-cylinder engines, including Crosstrek, Outback, Forester, Impreza, Legacy and Ascent, which makes it convenient for multi-car households or routine maintenance. The pack of six is practical for regular oil change intervals and the included guarantee gives reasonable peace of mind.

Key Features

• Wide compatibility: Fits many Subaru models and engine variants from 2004 through 2025, so users can replace filters across multiple vehicles with one part number.
• OEM replacement numbers: Replaces several factory part numbers such as 15208AA160 and 15208AA21A, which simplifies sourcing the correct part for service.
• 6 pack convenience: Supplied as a set of six, which reduces the need to reorder for routine changes and lowers per-change cost.
• Engine protection: Designed to remove contaminants that can cause power loss or starting issues, helping extend engine life when changed on schedule.
• Change interval guidance: Seller recommends changing oil and filter every 6 months or 7,500 miles, providing a clear maintenance cadence to follow.

Who It's For

This product is ideal for Subaru owners who run 4-cylinder engines across model years listed and want a reliable, direct-fit oil filter without searching multiple part numbers. It is also a good option for DIY mechanics who perform regular maintenance on several cars and appreciate the economy of a six-pack.

It is less appropriate for owners of turbocharged non-compatible Subaru models not listed, or those who require a filter specified exclusively by a dealer for unusual performance applications. Always check the owners manual and engine type before installing.
