    Default Brake Ducts and the M5 MTechnic Front Bumper

    What do people that add the MTechnic Front bumper do for hooking up the brake ducts? I cant seem to find the part # for the Brake Ducts listed on RealOEM in the Diagram. Does anyone else have a solution for this? - JT

    Its part of the install kit for the 540i. You can probably go to your local dealer and ask the parts dept. to find it for you. They are not that expensive, when I bought them, maybe around 10 for each side.

    Do you have the part #s? They are not listed anywhere on RealOEM. http://www.realoem.com/bmw/showparts...39&hg=51&fg=15

    I don't have the part number. It took a while for my part guy at the dealer to find it too. Probably need to go into the M-Tech package for the 540i to show the right number, it should also show the part for the Alternator duct.

    Hey Kriss thanks. Those are the ducts came with my car. I still have those for you if you want them. The ones I am looking for are on this diagram http://www.realoem.com/bmw/showparts...39&hg=51&fg=15

    Hi John, aren't they the same though. The 540i ducts and be adapted onto the M5 front spoiler.

    From what I've heard, the 540i ducts will work.

    the 540 ducts have a little larger opening, but the same mounts and such.

    Default M5 diff front bumper?

    Didn't the M5 have a diff front bumper than the rest of the e34s? IMO, that means the 94 540i brake air ducts may not work on the M5 bumper. What does everyone think?

    Correct. The 540 Ducts won't work. Those are what are on the car now and they don't match up. Real OEM shows a part in the diagram for the Mtech Bumper - however there is no part number that corresponds with the part in the diagram.

    What I am looking to figure out is what did others do to solve this issue. Thoughts? - JT
