F80 O ring Part #?

[lenzify]

Hello i found a couple of boost leaks with my 2015 M3 so i started to replace all my o Rings that i could find with the help of a smoke machine of course. Im down to the last 2 o rings that needs replacing but i could not find a part number matching both turbos.

Essentially what im asking for is the part number or links to the O rings that connects the lower intake pipe to the turbo on the front and back turbos heres a diagram circled where the O rings are located.

Thanks in advance

Hi,
Those arent boost leaks if they are b4 the turbo compressing the air... Dont worry about that too much.

You can monitor the boost levels to see if they are hitting their targets to check if you have a boost leak.
