Brand new member. Just bought this and installed the Roush CAI. There is an opening in the front of the Roush box that meets the existing ram air tube that brings in the air. I noticed that there is a very slight gap on the left side as you look down from the top. Another words its not flush but the majority of it sits flush against the Roush box. I know the factory box slips into this tube where the Roush sits flush against it. I assume this is fine but need reassurance. THXXXXXXXXXXXX
