Need Help Choosing the Correct Radiator for 2006 Z4

[Molosh]

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!

N52 Z4 autos have a unique radiator. Part number 17117551635.

Manual gearbox cars use an E46 radiator that's used on all manual Z4's, 2.0 N46, all M54's etc. 17119071517. There is a top seal 17117514403 that BMW say you need as well but this is just a rubber strip that goes along the top of the radiator.

As for which rad, a BMW one is always best of course. Nissens are okay, maybe Hella etc but you get what you pay for. A BMW one is good for 10-20 years.
