I have a set installed and BTW I love them... they have been in for about 6 months and they still look great and I still get comments about the leather smell

As far as the Air bags go its not that bad.
On the underside of the seat there are 2 connections to remove. One Grey and one Yellow if my memory serves me. The 2 connections are for the seat belt sensor and the air bag.
So in terms of removing the front seat covers it isn't that hard

Hope that helps.
