As spark plugs fire at an extremely high rate, these Professional Iridium spark plugs are under constant chemical, thermal ...
With an Ultra-fine Iridium Alloy Center Electrode Employing a high melting point iridium alloy for the center electrode tip, a fine diameter of 0.4mm has been realized. This fine electrode has led to a lower spark voltage and a large increase in ignitability, which draws even more output and accelerator response from the engine.
Fine wire plugs have more in common with traditional automotive plugs, in that a single electrode-consisting of a small-gauge wire-forms the spark gap with a center electrode. There are several variations in electrode designs within the fine wire and massive categories. In the fine wire group, the single iridium wire is the most common.
I went to buy a set of Bosch plugs for my 350, I was asked if I wanted plugs with a 1, 2, or 4 electrodes.
