This is the spark plug boot that comes on the M91 engine. I contacted Jin to see if i could purchase more, and he has now added them to his store. These are the best
boots i have found for these small spark plugs. They fit very snugly and you merely strip the end of the wire and insert it into the boot. The boot fits tightly enough to hold the wire against the plug with no special clips needed and because they are clear, you can see if the wire is making proper contact. Can't beat the price either.
I highly recommend these if you have model engines. Now if we could get Jin to make similar boots for the C-6 plugs, that would be great!

Bonjour Doug,
Why would we need to change the one we have on our M91 engine ? Personnally, I do not touch anything so I should not damage it.
10 is a great figure and I do not know 10 friends who have this engine  ;)

Since the M91 comes with these already, i assume Doug was referring to the M90, which comes with a less slick solution.
As far as the number goes, i agree completely, 10 is overkill for most of us  :)

Or just a reason to increase our gas engine collections  :D

I have at least a dozen other engines that use this same spark plug. My intent was for those who have other engines as well that often have no boot, just a clip of some kind. These little plugs will shock you just as much as a full size plug, and these are a great boot if you have other engines.
