E3 it's a hotter spark, better burn, saves gas = runs. yes it's still the e3.10 plug.


I have had good luck with these plugs. still running after 2-3 years and looks good. starts up just the same as like the first day of use.

All the plugs that are spoken in the post here are in the same compatible plug sizes a typical plug as like a RJ17LM is broken down as such...... R=resister J=14mm thread and 3/8 depth 17=1-25 auto,small engine,or ordinance engine application LM= specialty plug (designed for lawn mowers)
