428i M Performance Rear Diffuser questions

stormlv · 06-20-2014, 01:36 AM

I was thinking of doing some mods on my car and one of the things that I'd like to add would be the m performance diffuser.

I was looking on getbmwparts.com and they have the two variants for the 428i and 435i.

Since BMW made the 435d exhaust in the same style as the 428i, I guess I'd have to opt for that one.

My first question is then, if anyone has any idea if the two exhaust systems have an identical placement (ie if I can fit the 428i diffuser on my 435d).

The second question would be if anyone has a picture of it installed on a 428i.
After a bit of searching, all of the pictures I have seen are of 435i...

Lastly, it seems the guys at getbmwparts.com have pretty good prices for their products. I suppose some of you have heard of them or might have experience in dealing with them. Are these genuine OEM parts?

getbmwparts.com is a BMW dealer in Maryland so yes, everything they sell are 100% genuine OEM parts. But if you're in Switzerland, I don't think they do international shipping.

Thanks for the info!

Indeed, they don't do international shipping ... however they do hint that they could do this through BongoUS...

Although delivery is exorbitant to CH. Just get it delivered to a colleague in France and pop over to collect it.

The diffuser is exactly the same for the 25d/28i, 30d models.

Easy install. Snaps in at the top with a handful of screws at the bottom, about a 15 minute job start to finish.

Its also an easy install. Built in clips at the top & existing screws at the bottom. About 15 minutes start to finish. Got mine from getbmwparts.com Only prep work is gluing in the vent screens at the ends of the diffuser if you are going to leave it matt black like I did.

Thanks for the tip. Have you already dealt with them before?

I suppose this includes the 35d, right?
