Hey guys, I have to go get my 96 318is etested this week and was wondering if this piece thats circled in white needs to be hooked up to the air intake somehow. The car has a cold air intake onit and this part is just sitting under it so im assuming it came off the stock intake somewhere?? I dont see anywhere else it would go. I bought the car like this so im not sure. If this did come off the stock airbox, do I need it hooked up to pass an etest? Thanks for help guys..
