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

I'd like to know this as well, but I'm about to put some Bosch platinum plugs in my car

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?
