Also, the 2.0t coil have a easy twist on/off feature which makes replacing them extremely easy and insanely fast. And lastly they offer a much improved spark. Some Audizine users have said they have gapped their plugs up to .044" to experience a butter smooth idle and power delivery. No results on if this improves MPG but I have a feeling it likely will help maybe 1-2 mpg.

I just learned that 034motorsport.com offer the complete kit, but it's a pretty big investment. I might be interested in getting the wiring from them but I'm still pricing around for the coils and checking if a local machine shop could make the brackets if I can find the specs.
