Questions about a rear diffuser

rwp49 · 05-10-2011, 07:30 PM

I'm in the market for a rear diffuser for my 2011 135i. Looking at some pictures does water spray out the back from the rear tires? If so does that get the outside of the diffuser really dirty. Also I know the BMW OEM diffuser is expensive but is it the best quality?

There is CF diffuser from iCarbon and oem from BMW. You can also go the way of finding a shop to paint it gloss black or yourself if your are good at spray paint!

OEM is 79$ for basic BMW diffuser.

Can't answer your question about dirt since I don't have a 135i

The majority of the splash up from the tires is seen on the side of the rear bumper, it doesn't swing around and get on the diffuser.

3D Design has a good piece thats a few bucks cheaper...

I checked the price on this. Looks like it's sitting at 160 right now. That's a great price for a carbon fiber diffuser, especially compared to OEM. Anyone have any experience with this one? Looks nice...

Nvm that was a layaway price

I just installed the iCarbon one on my 2011 135i, and it looks f'n amazing! **********s has amazing deals right now on iCarbon stuff if you call them over the phone. The water splashes up on the sides of the bumper, no where near the diffuser. BMW is way too expensive. iCarbon is the best deal for the quality and the money.
