All you need is the 10mm

Stick with the factory oil pump for that MY. If you go with a higher flow pump you will just push more oil through the bypass and put more heat into the oil.

11mm pumps are made to flow more for dual AVCS cars.

12mm pumps are made for dual AVCS higher reving factory 2.0

If you have a built motor, it's common to upgrade pumps to meet the flow requirements of larger tolerances, cross drilled crank, etc....

If you have concerns with the pump that's in there I'd recommend checking it to make sure it's within the service limits. If it's not, replace it with the same.
