Has anyone ever used a spark plug that checked out OK on the spark plug cross reference sheet, but did not perform the same as the original?
I ask because my zero turn mower is a John Deere, with a Kohler motor, with a Champion spark plug.
The nearest local John Deere dealer wants $8 per plug (I need 2) for a Champion plug wrapped in John Deere packaging, while O'Reilly's has a cross referenced Autolite plug for $2.80
FYI, the spark plug is a Champion XC12YC cross referenced with an Autolite 3924
Thanks for your input
