Is any one running Iridium spark plugs and do you like them? I have been looking at the NGK iridium plugs and want to now if they are worth buying and will help and have longer life than the NGK TR55 or TR6.

I read about them in gmhightechperformance about the new ones ACDelco is comeing out with and they got good reveiws you can even run Nitrous with them without worrys. they're suppost to last longer and be stronger than the platinums

 

I do run nitrous and get tired of changing plugs with my longtubes. It is a real pain and a 2 to 3 hour job.
