Br9eya vs br9es

What is the difference between these two plugs besides the groove in the electrode?  The 9 tells me that the heat range is the same...why do I need to spend extra to replace the 'S' with a 'YA'??

The EYA is a "anti-fouling" plug. I use the EYA's in my ZRT6 and haven't fouled a plug since. Whether they are a resistor or non-resistor type plug, I am not sure.
