if you bought the Bosch super copper tips they should be wr7dc and the gap should be .028 in +/- .004
Autozone/bosch part number is 7900

Hi 
Sorry to disagree but "straight from the box" is NOT a good idea...
I have fitted thousands of plugs (when a race mechanic) and out of every box of 10, there are always variations in gap....
Feeler gauges and a 30 thou gap.....and check EVERY plug.....
All the best Brett

Ahh i think thats standard operating proccedure, always check the gaps before installing new plugs regardless of the printing on the box. And confirm the correct gap for each engine .
I suggest a bit of anti seize for the plug threads

When I bought my S2 ...it had Bosch Quads in it....and was running badly....they were fairly new as well...
I took them out and replaced with NGK BP6ES and ran perfectly afterwards...
Personal opinion only ...
