Plug confusion
About 40K ago I changed plugs to the Iridium IX. I actually didn't notice any performance improvement over the stock platinum plugs. Now I notice that my milege ras rolled off about 15% (I have cleaned the air filter and run injector cleaner through). My mechanic tells me that I put in the wrong plugs... that the Iridium IX are a great plug for NON platinum designs.
Does anyone concur with this??? I know of lots who have switched to the IX and really like them.
Would switching plugs help gas mileage??

And... a final question... what is the life of the IX plugs? Should I be changing them? I have 40K miles on them.
Appreciate your input!
