Hey All,

I just got back from the hobby shop and I have a quick quesiton. The guy at the hobby shop recommended I run a hot glow plug to increase performance. He said that by running a hot glow plug I wouldn't actually be increasing the running temperature of my engine - is this true?

Also, if running a hot glow plug will increase performance then what purpose do the "cooler" glow plugs serve?

Thanks!

small block engine use hot plug, big block engine use cold plug and when i run a hot plug in small block engine from a cold there is no difference mabye just easier starting

i personally dont see any difference, i always run hot and once ran a cold one and no difference at all

just use medium and forget about hot or cold.
