Bosch FGR 6 KQC or FGR 7 KQC.
Tightening torque = 30+3 Nm (22+2 ft-lb).
I've used both brands and found no difference in performance, though Beru is more expensive here in Oz.
A lot of discussions on if you should or should not use anti-sieze paste on the threads - I do but that because I'm a bit old fashioned and I once had a siezed plug on my SAAB which caused a lot of grief at the time. I would be surprised that your original plugs have suddenly loosened, but you never know!
Hope this helps.....

I'm thinking that a loose plug is probably a stretch on this one too. But, I'm willing to at least check them to make sure that one or more aren't loose. In any case, what's all the hype around iridium spark plugs ?
