Cosworth Main Bearing Set Subaru WRX/STI EJ20/EJ25 Standard

Engine bearings are one of the most vital components within an engine and are often overlooked when considering high performance upgrades. Performance engineered, multi-layer bearings generate less heat than normal bearings by reducing friction. Cosworth bearing sets feature a unique combination of design, metallurgy and engineering to deliver what drivers expect from high performance engine bearings.
