Been Curios about the Velossa tech. I've heard from a few sources that the ram air effect from the big mouth can cause too much air to enter the airbox and disrupt the MAF signal. Did you notice any driveability issues after doing the Velossa tech?Some the holes in these air boxes are there intentionally. Cp-e's intake has slits in the box for hot air to escape. And typically there is at least a hole at the bottom to allow any water seepage to drain out. IMO sealing the box can sometimes result in hot air getting trapped in there. That could be why your cruising temps are higher.
The way I did mine- I have the Velossa tech big mouth blocking off the radiator backwash and an open air box that seals fairly well to the hood but probably not air tight. Idling and cruising temps are excellent.
