I am looking to replace the sparkplugs and i have seen advice on performance forums to use copper or silver plugs instead of iridium for forced induction cars to prevent premature ignition due to heat in plug. I guess iridum will last longer 100k miles so that is why oems install iridium. I doubt through the remaining life of my car to put 20k miles on it.

Since they are the same price as quality iridium i am favoring the idea of purchasing the Brisk Silver.

Does anyone have any experience with using Silver plugs in an SRT6?

Just put the OEM plug in there and it call it a day. I bet your car is stock to right? Dont over think simple things.

 

Stock plugs are no longer being made. I'm having a hard time finding out what the replacement plug should be

I still like the laser iridium plugs the best for the SRT6, torture tested at 25psi without issues. if you plan on running nitrous we will have a different conversation but for boost alone, laser iridium's are where its at.

 

Needwings what pulleys did you stack to get 25 psi most I seen was about 22psi and that was on a 150 shot of nitrous with a 62mm
