The 2013 Subaru Legacy comes standard with a 2.5-liter naturally aspirated flat-four boxer engine producing 173 horsepower and 174 lb-ft of torque. This SOHC engine features aluminum construction with cast iron cylinder liners and utilizes port fuel injection. The horizontally opposed design provides a lower center of gravity for improved handling dynamics. The engine is paired with either a 6-speed manual transmission or Subaru’s Lineartronic CVT automatic transmission, with standard all-wheel drive across all trim levels.

The 2013 Subaru Legacy shares most parts with the 2010-2014 fifth generation Legacy models. The 2.5L engine components are largely interchangeable across these years, including the cylinder heads, pistons, and most sensors. Body panels, interior components, and suspension parts also interchange well within this generation. Some electrical components and infotainment systems may have minor variations between model years. The CVT transmission used in 2013 is compatible with 2010-2014 models equipped with the same transmission type.

The 2013 Legacy’s 2.5L engine is generally reliable but has some known weaknesses. While not as problematic as earlier EJ25 engines, it can still develop head gasket leaks and oil consumption issues with higher mileage. Regular oil changes every 3,000-5,000 miles are crucial, and owners should monitor oil levels frequently due to potential consumption. The timing chain design eliminates belt replacement concerns, and the engine typically runs well beyond 200,000 miles with proper maintenance. Overall, it’s a decent engine that requires attentive care.
