looking at your last post it looks like you might have bought a basic air intake instead of a Short Ram. It was explained to me that this style of intake connects from the intake resonator box, and the longer Short Ram connects to the throttle Body. Alot of the short Rams sold on ebay are actually labeled as Cold Air units... confusing
...but the Short Ram intakes that members have converted is actually a little longer than the unit you purchased. This is my best guess as too why the two intakes won't join up! Good luck
