I took out most of my intake to swap my old radiator out for an aluminum one and came upon two openings in my intake system one is connected and the other one i dont know. I found another opening in a vacum cylinoid i believe and thought it might go to that any suggestions?

here is the opening not connected to anything.

here is what we are guessing it goes to

suggestions please

That is just like mine... It looks like that goes to the back pipe and connects to it... Is that the original air intake? Reason i am asking is there all different to each engine or so i have been showen by my bmw mechanic... Example. a E36 318I L reg has a different intake to my N reg 318i E36
