As posted - Need somebody with experience to read these plugs. Based on reading and videos that I have done (probably worthless I admit) they look like I might be running lean. Anybody with real world experience think differently. These are the OEM champion plugs (2018 M240i B58) and stock GAP. Had these in for roughly 40k miles. When your looking at the pic Cylinder six will be all the way to the right. Cylinder 1 all the way to the left. Would appreciate the knowledge drop.

Those aren't the correct plugs, IMHO. They need to be NGK 94201 plugs. Those Champions appear to be too hot.

Thats what I just dropped in actually.

Good! As I noted, those Champion plugs look to be too hot. By too hot I mean the plugs don't dissipate heat as quickly as the stock plugs.
