Kohler Engine Spark Plug Application Chart

When selecting a spark plug for your Kohler small engine from another manufacture (NGK, Bosch, Autolite, AC) then listed here, it is best to use their reference catalog to see what spark plug they recommend for your Kohler engine. And if their catalog is not showing the engine you have use their cross reference chart from one of the plugs listed below.

Some plug listed are resistor type plugs and are usually identified by the (R) in the plug part number. Resistor type plugs suppresses the RFI (radio frequency interference) in your engine, without resistor plugs you can experience static on your radio as well as interfere with other sensitive electronic equipment. Some engines must use resistor plugs for a proper talkback to the electronic ignition.
