standard airbox help
 

got this in the general section but maybe you local guys have the knowledge......

fitting a standard airbox back on after general advice to do so..... taking off the k&n cone, but on my pipe that goes from maf to engine there was a hole in the old connector pipe which took something from a reservoir thing behind drivers headlight...... what is this? my new pipe doesnt have this hole.... so have i got the wrong hose from a later car? mines the inbetween 97/98 model.
cheers all!
