BMW Performance Diffuser!

Does anyone know a vendor that sells a "Non-Carbon Fiber" BMW Performance Diffuser for a 335xi e92?

Thanks

Tischer BMW aka getbmw parts

If your bay area
I can also direct you to a friendly bmw parts dept


I recently went through this

I learned hard way,
Perfirmance diffuser only fits on perfirmance bumper.
Not msport


Verify with your Bmw parts dept


I still can't believe it
Bumpers look identical
Just mm different

Msport bumper needs to be trimmed to fit the Performance Diffuser. Pretty sure I saw that in the official BMW install guide.

Hmmmm

Body and part shop just said not possible


If I remember. Performance diffuser seemed smaller not larger,
Also in question was one or two upper clip placements

At least one perfornance diffuser clip had nowhere to go


I do believe it can be made to work

Really unsure why BMW didn't synchronize diffuser sizes

Considering both bumpers visually look identical

See the PDF there, page 21, second picture "For vehicles with M package." Maybe that will help?

I have an 07 with full mtech package. I also have the OEM BMW perf diffuser. Some trimming on the bumper is needed (as said in the instructions) but it fits.

Is the trimming needed with the e92 bumper also? Or just the e90 bumper?

Just the e90, my e93 (same bumper as e92) required no cutting or mods to get the perf diffuser on.

Good. Thats what I thought. I just ordered an mtech rear and performance diffuser. They havent arrived yet so I cant test fit yet.

Thank you.

Bumping this up.

Did you mount the OEM performance diffuser on the replica mtech bumper?

only the e90 msport rear need to be trimmed, not the E92.
You can just swap the E92 diffuser without doing any cutting or trimming.
