is that right?

they are gapped at .05 cause of the ZX upgrade and MSD coil....should i gap them at .04-.045?

im concerned about the black ring around the outside.

all new sensors, new AFM, new injectors, new everything, and 5000miles on the rebuilt engine... i cant seem to figure this darned tuning thing out. UGH!
