Greddy Iriduim Spark Plugs - 8's - Set of 4

Product Information

GReddy Spark Plugs are designed in cooler heat ranges to reduce heat and chances of pre-ignition. The reason they are so durable is the very fine, 0.6mm diameter iridium electrode. Iridium Tune spark plugs are ideal for low to medium tuned engines, factory turbocharged engines, or bolt on turbo kit equipped vehicles.

* GReddy Spark Plugs use NGK heat range codes, so the larger the number the colder the heat range.

** ISO (International Standards Organization) - The ISO height for a spark plug from the seat to the top of the terminal nut is 50.5mm

*** JIS (Japanese Industrial Standard) - The JIS height for a spark plug from the seat to the top of the terminal nut is 53mm

**** L (Long Reach) - The L is similar to the ISO, however the treaded reach is 26.5mm instead of the normal reach of the ISO and JIS of 19mm
