Your English is a lot better then a lot of the people on this form that use it all the time. Being I only bash I run the glow plug they recommend. I use to have a link about glow plugs but cannot find it right now and if I do I will post it. I do know they recommend using a different one when you go to higher content nitro over 20% but I forget which way you go hotter or cooler but it is on this form somewhere.
