I like the High Compression glow plugs and use them if I don't use a Nelson glow plug with adapter head.
I also have a Valentine adapter head for the .09 that uses a turbo plug another good choice if you can
fabricate a turbo plug adapter for the .049 you will for sure see a jump in performance.

 

Hello !, you're right I made a mistake, it's like you say: "Glow Plug" :-)

Thanks for commenting your experiences, you know or have used in some Cox 049/051 the glow plug 061 AP ??

Mauricio, my favorites are the drop-in type that are held down with a clamp ring like these:

That Brodak link is a pretty good deal, and I think they are all made by Merlin. They are super high compression so take 3-5 copper gaskets. They fit all Cox .049 and Norvel .049 and .061. If I could have my choice of any plug and head, those would be it. A spring-clip type pocket glow igniter fits them too if you have the regular 3-fin clamp ring. the extra cooling 5-fin ring like Bernie sells for the Texaco has to be modified for that type igniter to fit.

Rusty !, thanks for the information and leave your comment.
So that I can understand, you say that this type of glow plug should be placed between 3 and 5 units of washers to lowering their compression due to the small dome with and increase the combustion chamber?....Mauricio.

That's right Mauricio. Start with 5 and work your way down. I have one TD .051 that is so worn out it only uses one, but that is not the usual case.
