Doing a header swap. other than lasting longer do the iridium plugs offer any added performance benefit?

Don't use BOSCH plugs in our cars. Most will say they started misfiring and crap. I have Ac Delco iridiums and there great. Don't have to change them for a long time.

Iridiums last longer so you dont need to change them as often. I have a good deal on NGK iridiums as well as a new plug: WeaponX iridium for a little less than the NGK right now.

damn I'm glad y'all said something I did'nt know bosch sucks, luckily I still have my receipt from advance. I guess I'll go with the plugs and wires package for $68. Is there a huge difference between the TR55s and the TR55IXs?
