There is a bmw part that will work and I can dig up the part number for you, but you will have to splice it into your existing intake somehow.

Thanks for the 3.25. I have a large collection of odd parts and I'm pretty sure I can find a tube that will work or adapt one. Audi A8 or Mercedes ML430 is probably about right.
