Are the tr55 plugs really better than stock?

[Street Fighter]

I have installed the tr55 plugs in my TA twice since I had it and I am yet to notice any difference in the idle of performance.If there is no difference I might as well go back to stock and get more time out of the plugs.Have anybody truly noticed any idle or performance change?:dunno:

They are copper tip plugs which conduct electricity better than platnum, however they do not last as long. It is all personal preference.

I like to change my plugs every 2 years, because of the dissimilar (sp) metals between the plug, and the head.
