Iridium Spark Plugs for an N16, worth it?

hi all

just wondering what the general opinion is on Iridium Spark plugs for Almera's generally or perhaps more specifically for the 1.5 petrol engine


many thanks
 
not sure what they would be like on our cars mate but i'm thinking bout trying them next year as they made my 2002 yamaha r6 alot smoother to ride and a tiny bit more power. or felt like it did anyway.
 
Longevity - yes.

Power - no.

I made more power with copper plugs than I ever did with platinums or iridiums.
 
well you wont have to worry about changing them for one......
All JDM QG series engines came with them..
how can you tell a spark plug made more power dude.. did you dyno your car under the same conditions
