11109AA131 is for the 04-05 STi. It's also used on early Legacy GT and Forester XT models too, since it's the same short block.

11109AA151 is for 06+ EJ25s (STi, Legacy GT & Forester XT).

From what I've seen the 06+ pan is a wee bit deeper (1/8" at best), and there are VERY slight diferences as stated above.

Something else to note is that the baffle tray (sheetmetal piece that bolts to the bottom fo the block) should also be changed when doing an oil pan swap. They are cheap, and specifically designed to work with each pan.
