What engine?

stock cen matrix motor

I've seen that there are long glow plugs and short glow plugs but what's the difference??
I'm sorry if i seem to be high jacking the thread but it seems un reasonable to start a new one for a simple question like mine.

A short plug is a few threads shorter than a long plug. If you use a short plug in a long plug application, engine may not run good or at all. All OS plugs are short plugs. Mccoy plugs are long.

and if you run a long plug in a short plug motor it will hit the top of the piston

come on anyone have a suggestion

If the engine can handle long threaded plugs then try a McCoy 8 or 9. If it uses a short plug try the OS#8 or A5 or R5.

I am currently using a Mccoy mc-9 (long thread?) within my hyper 8..well thats what I got with it and have the mac28 engine..I was wondering what spare glow plugs to get too but I jsut got some more Mccoy mc-9's to be safe.

Stick with Mccoy's, they are good plugs.
