LOL oh well we learn from our mistakes hey? Yeah hot plugs can be good but it largely depends on the type of fuel and the size of the engine. But for me I find that hot plug burn out too fast so medium hot plugs work better for me. Also the OS plugs are short reach so that has an affect as well. You'll probably find if you used say a medium temp long reach, like a Mccoy MC8 would work even better.
