T Tom Guest Sep 29, 2005 #2 Who uses silver and yttrium? The idea is to make the electrode harder and wear down less meaning longer service intervals. (note, not better performance) But most of them still seem to have steel/copper earth electrodes.

OP OP A Anonymous Guest Sep 29, 2005 #3 Bosch do an Yttrium plug. Silver - you read that most racing plugs consist of a silver centre electrode. The Bosch super 4's use a silver plated elecrode. I have also seen the Bosch super Yttrium spark plug. Just wondering which one is the better spark plug.
