Silverstone™:

STOP... playing around with spark plugs that feature fine wire electrodes, split electrodes, ring electrodes, multiple electrodes, platinum electrodes, copper electrodes, or gold electrodes, and get serious with silver electrodes! Silver is the best electrical and thermal conductor of any metal. This makes Silverstone™ the best spark plugs in the world. Period! Silver Center Electrode Up To 137% More Spark Power Increased Horsepower Cleaner Combustion Long Lasting Race Proven Design Top Quality Materials

Silverstone spark plugs are especially designed for the unique demands of modern high-performance engines. Silver is the best electrical and thermal conductor of all metals, which makes it the ultimate material for a spark plug's center electrode. The large diameter silver center electrode of Silverstone spark plugs increases spark carrying ability and spark power by as much as 137%. Silver is extremely resistant to erosion, guaranteeing a virtually unchanged electrode gap for the life of the spark plug. Silverstone spark plugs are designed without a suppressor resistor, perfect for performance enthusiasts who demand the most from their engines. For racing or dependability and efficiency for everyday use, Silverstone spark plugs deliver the most powerful spark.

If you're not using Silverstone™, you're not going as fast as you could be.
