I have an air raid on mine which leaves the BOX.
If anything I would just go to homedepot etc and buy the tube to extend and make holes etc for those 2 holes.......

I was looking at this setup yesterday and I see on the 02 envoy the very front right corner of this air box is a vacuum line plugging into it, I have not seen anyone mention that.

anyone know what diameter tube I would need? I think I saw someone mention 3inches.
