so that's very odd if it was like this

Things like bosch coils

TRW control arms vs BMW stamped M3 ones

mahle.. whatever (sway bars? they do the pistons as well i think, but i'm pretty sure they don't sell them straight to aftermarket hah)

they're a mechanically identical product from the original manufacturer at least on the E9x/E8x.

if it was a bosch coil from BMW with a BMW logo.. and a bosch coil in the 'aftermarket' that had mechanical differences

well it doesn't make financial sense, because it means different tooling, different etc. etc.. they'd lose money selling it that way?

I'm not talking about a manufacturer with OEM capability manufacturing a coil for the N54, but the actual original equipment manufacturer, like the initialism implies.
Yep i get it.
It might be that when they are manufactured to BMW (or any other big company) they go through a lot more quality checks

To me it would make the most sense that OE and OEM be 100% identical but i have seen it in couple occasions where OEM was lacking in quality or fitment.
