Bosch WR3CS Silver Spark Plug

Bosch silver spark plugs are engineered to improve performance in any sport or racing application. Specifically engineered for colder racing applications, particularly those that run at full throttle, and not for traditional automotive use as they would quickly foul out. Silver enhanced center electrode conducts electricity better than copper or nickel. Silver has a lower melting point than nickel, so these plugs are engineered for high performance, not long life, and have a shorter life span.
