NGK plugs part #

Ok so it would seem as though the thread that had the NGK spark plug part # was lost, anybody remember what it was? I am going to the track next friday and need to order the plugs. Before anybody says it I have seached the old threads and they dont have the spark plug I am looking for. Mystery???

goto sparkplugs.com and you can get tons of info on there if you want one step colder plugs with the proper gap get plugs for the K20A2 out of the type s years 2002-2003 that should work for you.
