Show original supplier description
The ACL Orbit High Performance Oil Pump is engineered to provide enhanced oil flow and pressure for Subaru vehicles equipped with EJ20, EJ22, and EJ25 engines. Manufactured by ACL, a company recognized for its engine bearings, this high-performance oil pump serves as a direct replacement for factory units, offering OE fit, precision, and durability. It is built with a 10mm housing designed to fit a 12mm rotor, aiming for increased output and volume. Flow data indicates a significant increase over the OE oil pump: at 600 RPM, it flows 8.5 L/MIN compared to the OE's 4.9 L/MIN; at 3000 RPM, it flows 28.8 L/MIN versus the OE's 16.8 L/MIN; and at 5000 RPM, it delivers 51.2 L/MIN compared to the OE's 41.3 L/MIN. The pump meets TSI6949 and ISO certifications and comes with a twelve-month, 12,000-mile warranty. This oil pump is compatible with a range of Subaru models, including the 2002-2014 WRX, 2004-2014 STI, 2004-2013 Forester XT, 2005-2012 Legacy GT, and 2005-2009 Outback XT. It is noted that some users have experienced issues with oil pressure on startup, with one reviewer suggesting it may be due to the 10mm housing with a 12mm rotor design compared to OEM 11mm or 12mm pumps, recommending a slightly higher-cost OEM unit for immediate oil pressure. However, other users report good flow and construction, with one mentioning it flows more than the factory STI 13mm oil pump.
