For any one that went with a CAI did you get the right part to cover up the hole in the fire wall when you remover the sound tub?.
Some of the manufacturers out there give you a hole plug but its not the right part to use, it does not seal the fire wall, and you end up with two slots still open from the plug, we found out when we did an install on a 2SS, then we looked at the 2.0T car we have in the back and it came with a GM plug that filled all the opening and used the nut from the firewall to hold it in place.
2.0T car.
New part.
