Fiesta ST180 DENSE Iridium POWER Pinpoint electrode Spark Plugs.

By harnessing the power of Iridium, Dense is able to shrink the surface area of the center electrode - the most critical component of a spark plug. Unlike the typical platinum plug that has a 1.1 mm diameter center electrode, the Dense Iridium Power Spark Plug has the World's smallest center electrode measuring only .4 mm in diameter.

The Spark Plug can be an important tuning tool for your engine...

You use a hotter plug in cooler conditions and cooler plug in warmer conditions. When you go from a cooler to hotter plug you are leaning out the motor slightly.
