Yes, very very sweet !! Been waiting for such a piece. I was seriously thinking about taking the stock unit and port and polishing it to get a better flow through it. This unit will do the trick very nicely.
Now with an opening to full size like this one ....

Doing a small amount of polishing and smoothing the edges, it will make for some serious flow
Polish the internal to the fullest extent, soot build up will drop to nothing since it will have no pores to stick to. Do the same to the manifold and soot build up in the intake would be null !
Been thinking about that same tool for a long time, so far, been able to do all my work without
Cheers,
Roberto
