#1 or #2 is what you want

They are both one heat range cooler. The third one has a gap that is .044 thats way to out of range for what you need - you should be looking at .028-.032.

Choose #1 if you want to change your plugs every 20-30k

Choose #2 if you want to do it every 5-10k

Both cars can use the same plugs

Yep the cheaper ones have a copper core(just like the stock audi plugs) and the others have a iridium center electrode for longer life. Most people just get the regular Bk7RE's and change them every 10-15k - or - every other oil change. Since its such a simple job

stock audi plugs dont have copper cores.. especially not 18t ones. i could be wrong but i think all oem vag plugs are iridium core

There is a picture of a spark plug, and notice I didn't use the word "iridium core". But you are right, OEM do have an iridium center electrode.
