Okay so I took it off when orignally wanting to remove the intercooler because thought on the 335is was a bit different... turns I probably wouldn't even have to take it off but anyways..
I wasn't able to reinstall it back and I even broke part of it I think.
Anyone has any clue as to what this is and does and if it's crucial? It went directly under the intercooler. Can't find the name of the piece on real oem.
Here are pictures of it.
