How many filters are in a Subaru Crosstrek?
Three primary filters keep the Crosstrek's systems clean: the engine oil filter, the engine air filter, and the cabin air filter. There is no separate, serviceable fuel filter in most Crosstrek models.
The question centers on how many filters are used and which ones require regular replacement. While three are standard for routine maintenance, some readers wonder whether a fuel filter exists at all, since Subaru commonly designs the fuel filtration within the fuel pump assembly rather than as a stand-alone service item.
What filters does the Crosstrek have?
Below is a concise list of the main filters you will encounter during routine maintenance.
- Engine oil filter
- Engine air filter
- Cabin air filter
These three filters cover the essential air and oil filtration needs for everyday driving. Routine replacement is typically aligned with maintenance intervals in the owner’s manual and can vary by model year and driving conditions.
Fuel filtration in the Crosstrek
Most Crosstrek models do not use a separate serviceable fuel filter. The fuel system relies on filtration within the fuel pump module mounted in the fuel tank, with no regular replacement interval for a standalone filter.
Summary
The Subaru Crosstrek relies on three primary filters: engine oil, engine air, and cabin air. There is no separate fuel filter in typical Crosstrek configurations, making three filters the standard count for owners and service technicians.
