I bought my 316i coupe last week nd it came with a stupid small k&n cone on it, so today I took it off to fit a standard airbox nd noticed that something behind it wasn't attached to anything? I dnt knw what it is? Its attachd to the afm nd other things and has a blue pipe coming off the end... The bracket has snapped nd nw am worrying. It has bmw 1 180 886 ak9/1 on it if this helps? Cheers guys if anyone could tel me what it is?
