i got the 1.8 miata. and i've had an injen intake filter on it for awhile. and im about to change the stock piping for an injen pipe,
but there is a small U shaped hose (with 2 clamps on it) at the bottom of the stock intake pipe that goes to somewhere around the bottom of my intake manifold,
and there is no spot for that on the new pipe,

will it hurt to not have that connected? or should i just leave the stock pipe?
