can a four spoke 2007 a4 steering wheel fit in a 2006 three spoke steering wheels place? or will i have to change the airbag as well?

 

Why? The 3-spoke looks and feels so much better. I love my 2006 3-spoke wheel, but it did have to grow on me.

 

I think they should be interchangable. Airbags are contected by a wire plug. And a 2006 is not really too different than a 2007/2008 B7. 3 spoke or 4 spoke, I guess it depends on the wheel itself. I have had both, but I like my current 4 spoke leather wrapped multifunction wheel the best so far.
