2007-2014 Subaru Impreza & 2015 Subaru WRX STI 2.5L H4 Master Engine Rebuild Kit
Partsology offers the OEM quality EK722CM master engine rebuild kit designed for the 2007–2014 Subaru Impreza and 2015 Subaru WRX STI equipped with the 2.5L H4 2458cc 16V DOHC turbocharged engine, a performance-focused boxer engine known for its balance of power and efficiency in Subaru’s AWD lineup. This comprehensive master rebuild kit is engineered to help restore factory-level performance and prolong the life of your engine by addressing critical wear components, making it an ideal solution for high-mileage vehicles or engines experiencing issues such as oil consumption, knocking noises, loss of compression, or excessive exhaust smoke. Commonly driven enthusiast vehicles, both the Impreza and WRX STI, benefit greatly from proper engine maintenance, and rebuilding with a complete kit ensures longevity and reliability under daily driving or spirited conditions. The master engine rebuild kit typically includes essential components such as pistons, piston rings, main and rod bearings, gaskets, seals, and often an oil pump and timing components, providing a complete solution compared to a standard engine rebuild kit, which may only include basic internal parts and not the full range needed for a thorough overhaul. Rebuilding your engine with a master kit not only improves performance and fuel efficiency but also helps avoid the cost of full engine replacement while restoring confidence behind the wheel. Partsology supplies OEM-quality engine parts at amazing prices with next-day shipping, making it easy and affordable to bring your Subaru engine back to life.
