Quick Overview

This is the high performance NGK Iridium spark plug for a very wide variety of engines.  If you are rejetting the carburetory, you will definitely want to use these for best spark and performance!

NGK Iridium spark plugs are pre-gapped. The manufacturer does not recommend re-gapping them as you will likely break the electrode.
