Pretty much same as new
I have the old tips and the lens kit, which I believe is airtech, but I do not have the box near by. I have not installed it yet, but have seen 2 aircraft with them. They look pretty much like the new tips. There is a fiberglasss bulkhead with lens recess, you "glass" in after making the appropriate cut-out. It comes with lens that you then put on. Not any very noticeable difference between the two installations, but as you can imagine, final fit and appearance is up to the "craftsman" involved.
