Imported directly from Subaru of Japan to our offices in the USA, the 12mm oil pump is ideal for any high horsepower engine requiring proper lubrication. At 12mm in size, this pump nets a higher flow rate than the Subaru 10mm and 11mm oil pumps (found on the USA ej25 WRX and STI). The pump physically appears the same on the outside, and uses all the same parts (gaskets, timing belt guide) as the 10mm and 11mm pumps.
- direct factory fit to any EJ20 or EJ25 block circa 2000-2021
- can be used on a stock engine without issues
- uses the same crankshaft seal (806733030) and oil pump seal o-ring (10991AA001) as the 10mm and 11mm oil pumps
