The 2008 Subaru Impreza comes with a 2.5L naturally aspirated flat-four boxer engine (EJ253). This horizontally-opposed engine produces 173 horsepower and 166 lb-ft of torque. The boxer design provides a lower center of gravity for better handling and smoother operation due to opposing piston movement. This engine features single overhead cams, multi-port fuel injection, and an aluminum block with cast iron cylinder liners. It’s paired with either a 5-speed manual or 4-speed automatic transmission and Subaru’s standard all-wheel drive system.

The 2.5L EJ253 engine in the 2008 Impreza is moderately reliable but has known weak points. Head gasket issues are the primary concern, typically occurring between 80,000-120,000 miles. Regular maintenance is crucial – change oil every 3,000-5,000 miles, replace timing belt every 105,000 miles, and monitor coolant levels closely. The engine can last 200,000+ miles with proper care and timely head gasket replacement. Avoid overheating at all costs and address coolant leaks immediately to prevent catastrophic damage.
