Spark Plugs Preferences

I'm about to buy new spark plugs and wondered what peoples preferences are now? Any links would also be greatly appreciated. Thank you in advance. Ian

Probably find them cheaper elsewhere but gives you an idea.
These are identical to what Audi/TPS supply other than the box and maybe VAG being written on them.
Think there has been one or two previous plugs supplied but these are the latest with three electrodes.

Thanks for the info. I see when you cross reference, the part numbers the same - 101 905 621. Don't think my ones now have the three electrodes. Is this something new?
