gotcha. what bothered me is that everyone said the updated would be cast with the part number but instead its only printed on, which plants a seed in my mind always wondering if the intake that came off was indeed updated...but the old intake had grooves inside where the butterfly valves hit...which just got me thinking maybe the updated intakes movement of the butterfly valves has been limited causing it not to make contact with the walls thus reducing risk of malfunction?.?. <img src="/forums/images/graemlins/confused.gif" alt="" /> <img src="/forums/images/graemlins/scared.gif" alt="" />
