Question about TR6 spark plugs for nitrous
I havent used TR6s in awhile, i used another brand for few months and now decided go back to NGKs. I ordered them from advance and i dont remember them looking like this. They are real shiny polished silver where i thought they were more dull and they have V-Power stamped all over them!!! Is this a different type tr6 or did they have a make over?
