Whats the best spark plug for S52

[r55065]

Hey, Finally made it here with my first post.
Just finishing up small details on my 97 Arctic Silver sedan with a 98 S52. No automatic here!
I just finished clearing all the codes except for misfires. I'm ordering spark plug boots across the board.
The car has some sort of Bosch plug with 4 grounds.
What is a good plug for this engine?

I'll post some pics later....

Stick with the stockers! Should be a Bosch FGR8KQE if I recall correctly.
Although I have heard some really good sucess stories about the pulse plugs....maybe next time
