2003 Subaru Forester Engine

The 2003 Subaru Forester engine listed here is the EJ251. This reference covers the engine identification for this model year; it does not provide power, torque, displacement, fuel economy, or other engine ratings. Check the vehicle’s door jamb or owner’s manual to confirm any specification not shown here.

The listed engine code identifies the engine family, rather than detailing every configuration or rating. The available facts name only the EJ251 and do not indicate any engine differences by trim or other variation for this year. Do not assume that a rating or feature applies based on the engine code alone.

For confirmation of the engine and any specifications relevant to a particular vehicle, use its owner’s manual or vehicle identification information. If a figure is not listed in this reference, verify it in the owner’s manual rather than relying on an estimate.
