searched with no results....this company has been around ....and i made more power using their wires and plugs in the past.....i am surprised not many of you even know of this company.....any feedback on the silver spark plugs from them let me know.....it's been narrowed down to these or brisk silver racing plugs to try out next......getting tired of paying out the *** for the ngk's iridiums.....and their copper ones burn out faster

 

the ngk iridiums are like $7 bucks a plug. the silvers are the same. i looked at those for my lightning, but just went with iridiums instead. iridiums last 100k. not sure about the wear characteristics of the silvers. they supposedly fire hotter cause the silver is a really good conductor. sorry, not much help. good luck.
