Review
Best plug to use in my powerful ride! Now I am able to dish out almost every horsepower that was hibernating when I was using the other spark plugs. Will not cause detonation and will not break off like the worst plugs made in the world - platinum. Everyone knows copper is the BEST conductor with the strongest spark; they are just to lazy to change them out as often as they need to. All in all, I find these spark plugs a little expensive, but for its fantastic performance, I guess it's all worth it.

What I like
Ensures better performance of my engine for my car to perform at its best.

What I do not like
They are quite expensive.
