What Spark Plug Should I use??

Hey guys i was just wondering what spark plug would be a good idea to run on my car. I know i need to run a colder spark plug but if i could get your guys opinions on what kinds to use. Im running a 2000 formula with a P1sc kit using a 4.00' pulley and probably producing around 6 to 8 lbs of boost.I do have my fuel system upgraded to allow the forced induction but im still undecided which plugs i wanna go with. Thanks for any info.
