Question about what e53s came with full air suspension

[4.8isX5]

I know some of you here know the specifics for this (hopefully),

So i believe all 4.8is came full air susp stock, 04-06 model years,


Now theres the rest of e53s 3.0/4.4 that are either full springs or rear air only,

Which model years in specific came with the option that you could get full air either on 3.0/4.4 maybe just 4.4, i think 4.6 you couldnt option that way, but i remember seeing somewhere other e53s which were not 4.8is could? Maybe i read wrong but i just want to know for sure.
