GReddy Iridium Tune Spark Plugs are designed for reducing heat from mildly tuned motors. For instance factory turbocharged engines which just want to boost up a little bit. The use of iridium electrodes helps to insure a long plug life. Our special ceramic insulator is used for increased heat transfer. The higher the number the colder the heat range.
