Parts for your 2022 Subaru Impreza-Head gasket

2022 Subaru Impreza head-gasket — what it does and when to act

Yes, the 2022 Subaru Impreza uses head gaskets. Technical sources including Subaru’s FB‑series Engine Service Manual (FB20) and the Subaru FAST parts catalogue/TechInfo confirm the 2.0‑litre FB20D horizontally opposed (boxer) engine runs multi‑layer steel (MLS) head gaskets—one per cylinder head, because the boxer layout has two heads. So a head gasket is absolutely relevant to this model.

The head gasket’s job is to seal three critical paths between the aluminium cylinder head and the engine block: combustion pressure, engine oil, and coolant. On the Impreza’s boxer engine, the MLS gasket manages heat cycles and clamping loads across a wide, flat interface, keeping compression tight while preventing oil and coolant from mixing or leaking. When it’s healthy, you’ll never notice it
