I made a decision early in my automotive career to only use OE plugs. AC in GM, Champion in Chrysler, Motorcraft in Ford, etc.
I continued with that choice for the power equipment trade and I have no complaints. There are some OPE applications I prefer to use NGK over Champion.
I've seen a lot of the older customers install non resistor plugs in applications that require them such as some MTD and Husqvarna handheld products.
Had a new customer that had his Husqvarna trimmer diagnosed by the big box store repair service as a "bad carb". Only thing wrong was the spark plug was non resistor.
