Are they the best? IDK, but they can sure take a lickin'; longest lasting plugs I ever had. My old 340s would burn 12s up pretty regularly, but those were not coppers.
I bought a new set in 2004 for to go to the track with.... The first set looked pretty good, and the car went 93(Eighth) on them. So... the new ones are spares and still in the trunk.
