Did my search on the forums, of course. I lost my manual that I just got on FCs. What are the measurements for our spark plugs? I remember that they are different sizes for some reason or other. And does anyone have a diagram of the electrical system? I think my spark plugs are stuck (that is, if I'm looking at the right place)

thanks for the help

 

Here is a handy link about pulgs.

Link to Mazdatrix plug info.

FWIW Rotaries eat steel leading plugs after 20K miles.
I use platinum leading & steel trailing.

 

Damn, thasts a great link.

Its not too technicial, not too brief. Just right.

Sounds like goldilocks and the 3 bears.

 

Makes me wonder if I should be running 'hotter' plugs to keep them from fouling and carboning up as most of my driving is done in town?

Did I miss it, but it didn't say if the hotter plug if run 'around town' would help to make the engine run cleaner, that is "less carbon buildup" in the engine?
