The 2008 Subaru Legacy comes standard with a 2.5-liter SOHC flat-four boxer engine producing 170 horsepower and 170 lb-ft of torque. This naturally aspirated engine features Subaru’s signature horizontally-opposed cylinder layout, providing a lower center of gravity for improved handling and stability. The engine utilizes a timing belt system and requires premium unleaded fuel for optimal performance. Standard all-wheel drive comes with this engine, making it capable in various weather conditions while delivering approximately 20/27 mpg city/highway.

The 2008 Subaru Legacy shares most parts with the 2005-2009 fourth generation Legacy models. Engine components, suspension parts, and many body panels interchange across these years. Some electrical components and interior trim pieces may have minor variations between early and late production years. The 2.5L SOHC engine remained largely unchanged throughout this generation, so major components like cylinder heads, blocks, and intake manifolds are typically interchangeable. However, always verify part numbers for critical components like ECUs, airbag modules, and transmission control units.

The 2.5L SOHC engine in the 2008 Legacy is moderately reliable but has well-documented head gasket issues that typically surface around 100,000-150,000 miles. When properly maintained with regular oil changes every 3,000-5,000 miles and timing belt service at 105,000 miles, these engines can reach 200,000+ miles. The boxer design provides smooth operation and good balance, but the horizontal layout makes some repairs more labor-intensive and expensive. Regular coolant system maintenance and monitoring for external leaks can help prevent major problems.
