tell me what do you think...

 

I dont have any experience with these plugs but among all the plugs I have used in the past my best experience has been with the JDM Denso Iridium plugs. Good luck

 

but what is the point to put an iridium spark plugs if the tC have already iridium plugs stock? (somebody told me that)

 

ooooooh, those look pretty..................don't waste your money, you would get better performance from adding trd valve stem caps.

 

any help?

Copper plugs have a different burn to them and are good in boosted cars, however you need to replace them every 3-5k miles.

 

Replacing Iridium plugs with Copper on a rather stock motor would be retarded as hell. The only reason you would need to do that would be for cooler burning in an application such as Turbo or Nitrous.
