Saw this and was wondering what you guys think. Seems similar to porting as far as smothing things out, but will actually narrow opening a little.

seems like a fairly solid idea... smooth the flow, get more power... you have to wonder if its not a gimmick kinda like a tornado though...

 

I'm confused as to how that can help matters. How is a plastic insert smoother than the throttlebody itself? And how can it reshape the air? It looks like there are tiny fins inside the insert but you can't really tell. I seriously doubt the power gains they are boasting. Is this to be used with a throttlebody spacer or without?

 

I'd say just get it ported

 

Look at the dyno sheet, same max HP. I have seen the same results (on the dyno) with a decent TBS.
