Direct replacement for my J Deere GT225
Fit my John Deere GT225 as a direct replacement. It did need to be re-gapped before installation. I think the price was fair for two spark plugs, now I have a spare.

Fits well, sane quality as the oem installed
Works really well, it fits and matches the original spark plugs and very easy to install. Very affordable! It starts right up , quality is very good and didn't have to adjust the gap on spark plugs!
