Hi there all,

I was just wondering that there are assorted glo plugs available, some have long heads, some have short heads, some have open filaments, some have a metal strip on the top of filament crossing from one end to another. My question is, if a gloplug has long head does it make any difference in any engine or short head one would work better? Gloplugs can be used for any engine either 2 stroke or 4 stroke and whatever the engine displacements are? or recommended or some particular gloplugs should be used.

Thanks

Mody
