Hey guys, I could use some help. I’ve got a 2006 BMW Z4 3.0i (VIN: 4USBU33576LW69731). I already ordered one radiator that was supposed to fit, but it turned out not to.

Now I’m not sure which part number is the right one. Does anyone know for sure which radiator I actually need? Appreciate any tips on OEM vs aftermarket brands too. I’m attaching a photo of my old radiator for reference. Thanks!
