M sport bumper fitment issue

[Wilsonv]

I understand there are many threads on Msport bumper installation on Non M z4.
But i have never gotten an answer from anyone, whether its post replies or PM.

So could someone please tell me would i need to buy a set of new airducts to fit the bumper? As i am going to fit it this week, and don't want to bring it back if the mechanics can't do it.

Thank yoU!

You can leave the air ducts out no problemo. You just need the bumper skin and the 3 grills. Operating temperatures seem the same to me.

THANK YOU!

I see, what exactly are the functions of the airducts?

To duct air and seal proper to the different shape of the "M" bumper, minimize wind noise, flapping parts, etc. If you have a N54 Twin turbo engine it is more important that the air be properly ducted to the oil cooler

You only need 4 placstic parts at about $100 US to do it correctly. Or as suggested just leave the parts off or rig the old pieces together with duct tape and cable ties.
