About NGK
A fresh plug is one of the cheapest fixes for a saw that is hard to start or running rough. NGK makes plugs in many sizes and heat ranges, and the code on each plug tells you its thread size, design, resistor type and heat range, so plugs are not interchangeable just because they look similar.
Always confirm the right plug in your saw's operator's manual, check the gap before installing, and read the old plug's color for clues about how your saw is running.
