Here goes nothing. I am driving a 325 ti compact sport that has a K&N induction kit fitted. The original airbox and ancilliaries are all in a cardboard box. My question relates to the item of kit below the induction kit and what it is, along with whether there are any detrimental effects to its no longer being involved in the food chain.
The old/original fitment pipe had an additional vertical pipe about 5 inches long coming out through the bottom of the feed (around 2 inches from the MAS) and going to a metal box. The rear of the metal box then opening into the empty area behind the suspension strut (why dont they have the battery in this area by the way? seems more logical than having it in the boot? unless balance is an issue?)
Anyway. My main questions here are:- What is this (now excluded) component? Is it's disconnection from the chain of airflow important or does it still do something regardless of its being left out in the cold? and finally, why does the induction kit dismiss the components fitment? Basically, I am worrying that it may be something important that is being ignored.
I have included a picture of the original pipework showing where it would have fitted (the vertical pipe is still in situ in the vehicle so isn't visible here) along with a diagram of roughly what I am talking about. The only image I have of the engine bay at the moment doesn't show the pipe unfortunately, but I have included it in case it jogs someones memory.
Trawling the web found me nothing, and asking a dealer isn't something that comes naturally (probably charge me 50 quid for just saying hello), so I throw it to the knowledgable masses of the forum and hope you guys can help.
Sorry the pictures are so large. No software on this pc to resize them.
