1994 Plymoth Duster Question

i have a 1994 plymoth duster 3.0 V6 and i just put a K&N intake on it and i want to take the stock airbox out but it has a few small tubes goin into it from under it. i was just wonderin if i should take it out anyway. what are them little tubes for.

those little tubes are for you crankcase ventilation system. It allows your crankcase area to vent blow-by gases and injest fresh air in that area. Simply removing it would case the pressure inside your crankcase to build up and cause serious bottom end damage, i.e. blown seals, bearing failure, etc.
