[s-cars] Spark Plugs

[Matt Molyneux]

I know everyone will want to jump all over me, thinking this is a dumb 
question that has been asked a million times, but, what are the BEST spark 
plugs for the S4/S6? I remember reading that the best plugs for these cars 
are still the OEM plugs, but I don't know the part number. Also, has anyone 
ever bought one of these (bottom of page, spark plug/air filter/oil change 
kit):

It looks like an awesome price if it does indeed include the right plugs. 

Because the dealer just quoted me $800 to do this service (plugs, filters, 
oil, fluids), which makes me want to vomit, I'm planing on doing it all 
myself. Is changing plugs on this car difficult? Does anyone have a BTDT or 
an earlier post that they can refer me to? Thanks for any help.
