Is the Tower plug same as the OS #8???
 

Greetings,

I am unable to find any info on the Tower plugs. They "appear" to be made by OS. Does anyone have a clue to this or the heat range?

Also, why in the world are OS plugs so short when used in long reach applications? This leaves bare threads exposed inside of the head.

Thank you for any information,

Ernie

Tower Hobbies glow plugs are made for them by a large manufacturer overseas. We don't have the information you're looking for. You'd have to contact Tower to see if they'll release that information.

O.S. glow plugs are manufacactured to fit a wide variety of engines. On some engines they may be a bit short, on others a bit long. They're fine in O.S. engines.
