There is no single universal oil filter part number for all 2020 Subarus—the correct number depends on your engine and model. In practice, a 2.0-liter engine uses a different filter from a 2.5-liter engine, with occasional trim-specific variations. The safest approach is to confirm via VIN or engine code.
Engine variants and how they affect the filter
To understand why the part number differs, it helps to know the two main engine families Subaru used in the 2020 lineup. Each family uses its own OEM filter, and some trims may add minor variations. This section outlines the two broad engine categories and why they matter for selecting the correct filter.
- 2.0L engine family (commonly FA-series engines, such as FA20)
- 2.5L engine family (commonly FB-series engines, such as FB25)
By identifying which engine your vehicle uses, you can narrow down the likely filter design. Always verify with official documentation or a parts lookup using your VIN to ensure an exact match.
How to confirm the exact part number for your vehicle
Use these steps to obtain the precise oil filter part number for your specific 2020 Subaru. This process helps avoid ordering the wrong model, especially when dealing with close-but-not-identical filters.
- Gather your vehicle’s VIN and note the engine code if visible.
- Visit Subaru’s official Parts Catalog or contact a Subaru dealer and enter the VIN to pull the exact parts list for your car.
- Check the oil filter currently installed or the packaging on a replacement you’re considering for the OEM part number.
- Cross-reference the identified part number with compatible aftermarket filters, ensuring correct thread size, gasket type, and overall dimensions.
- If in doubt, call a dealer or a trusted auto parts retailer with your VIN and engine code to confirm the correct option.
Using a VIN-based lookup minimizes the risk of ordering the wrong filter, which can differ in thread pitch, gasket size, and capacity between the 2.0L and 2.5L engines.
Practical tips for a smooth replacement
Whether you buy from OEM or aftermarket, consider these practical notes. Confirm compatibility with your service manual, and ensure the filter you choose matches the oil type and capacity recommended by Subaru for your engine. If you’re performing the replacement yourself, have the correct tools and a catch pan ready for the old oil.
Summary
In short, there isn’t a single part number for all 2020 Subarus. The oil filter you need depends on your engine—typically 2.0L vs 2.5L—and sometimes trim-specific variations. The most reliable method is to verify the exact part using your VIN or engine code through Subaru’s official parts catalog or a trusted dealer. By confirming the correct filter location and specification, you’ll ensure proper fitment and ongoing engine protection.
