This is the OEM 11mm STI oil pump for Subaru 2.5L engines.This will fit all WRX and STI 2.5 EJ25 motors. We strongly suggest replacing your oil pump when ever you need to replace the timing belt or if you are having any sort of engine internal work done to a WRX or STi.
This is a must when converting a 2.0L car to an STi shortblock, as it is not included and the 2.0L pump will not fit the 2.5L.

I installed this on an OEM EJ255 block. I was getting 20-25 PSI hot idle, 50ish Warm idle, 85-95 WOT, 95-98 cranking. This is all on stock clearance and 5w-30. Great pump, primed well. No issues. Relief opens without any issues.
OEM part. Arrived quickly. Perfect fit
Can't beat oem quality in certain parts. To me. This is one
Needed a new one for my engine rebuild, easy to install and is working well.
