In my opinion, you should only be looking at the OEM performance intake if you are looking to upgrade from the euro box. It has a larger snorkel for increased intake side. I have the standard US box, and for the money, will likely install a euro box before looking at an AFE solution. If I can be patient, I will get the PI.
