Subaru OEM 2.5L 11mm Oil Pump 2002-2014 WRX / 2004-2021 STI / 2005-2012 Legacy GT / 2005-2009 Outback XT / 2004-2013 Forester XT

This is the same oil pump that came stock on the 2008 STI. This will fir all WRX and STI 2.5 EJ25 motors. These have an 11MM pump that flows more volume then the standard pumps from the 04-07 STI, so these make for a great upgrade when you are building the motor, or changing the timing belt.
