4 cylinder sparkplug number & source?

[Dbaumanjr]

Hi all,
We are wondering what the Sparkplug part number is for a 4 cylinder mule? And where can they be sourced from?
As always, Thanks in advance!

I used Champion Xmj20 Industrial Spark Plugs in my 274 and 274A1. I believe that another plug is called for in the manual, but the xmj 20 is a replacement. I found mine by searching on line, several different sources came up. Lance Miller. Never mind what I say. Go with muleman's advice below.
