IAG Stage 2 CNC Ported EJ25 11mm Oil Pump for 04-21 STI, 02-14 WRX, 05-09 LGT, 04-13 FXT

The 11mm Subaru Oil pump is one of the most popular off the shelf pumps to use on EJ25 engines. Originally equipped on the 2008-21 STI Dual AVCS engines, it provides an adequate amount of pressure and flow that fits the needs of many OE and built engines. But, as with almost anything, there is room for improvement. The IAG Stage 2 CNC Ported EJ25 11mm Oil Pump design allows for increased flow volume and pressure, ensuring that the bearings have a sufficient oil film under all power levels and driving conditions. The additional oil flow to the engine provides a greater oil reserve to operate the AVCS solenoids and cam gears - giving you more consistent performance results.

This is one of Andrew's personal favorite products.
