I know I have the summit hi-output coils, and the copper plugs didn't last long for me

I noticed a nice change with TR-55 Copper plugs....

I dont mind changing them more since they are like 12 bux instead of the crazy prices for the fancy ones that many say arent quite as good as a nice copper.

Going from the stockers which are meant more to just last a long time, I think the copper was a nice choice.
