That all depends on what is fitted now. Just order the appropriate ones.

It doesn't matter, although the T-shape ICV is more common. Just match the boot to the ICV shape, and make sure you also have enough exit pipes to the brake servo. I used the same boot on my 320i and 325i.

If you're not sure, use Google Images to search each part number.

thank you for the info, clear now.

The brake servo feed from the boot is only used on early versions of E30s, and the whole over complicated set up can easily and usefully be disposed of if you end up with a boot without the stub pipe.
Simply connect a length of vacuum hose from one of the stubs on the throttle body to the servo via a simple one way valve, which can be obtained from virtually any car, including M40, M50, etc. engined BMWs, and block any remaining port.

thank you brian it is new idea for me as my old engine is m40 so does the servo.
