I have one plane that has 400+ flights, over 70 hours total flight time, that is still on the original glow plug in it. It's an OS 56 4-stroke with an OS "F" type glow plug.

Although i think we can saftly say dont count on this, MOST plugs dont get really that much time on them.
Why not? I only used 1 new glow plug last summer. If you don't run your engine too lean there is no reason in the world that they won't last for a long time. Another thing that can shorten glow plug life is leaving the glow driver on the plug for long periods. I'm not saying that glow plugs will last forever, but if somebody is going through glow plugs quickly there is probably a reason why.

Although it is true that it COULD last forever im sure you have bough glow plugs that lasted all of about 1 second (factory defect) as for tunning it does play a huge roll as to how lonjg the plug will last,
Now the glow ignitor in IDEAL situations you should be able to remove it right away and this will help the plug but if your fling in the winter you need to leave it on a little longer untill the engine warms up, no one in our club has found a different way of doing it you leave it on at addlie for a minute or so (not at full power this will destroy plugs)
Also engine break in CAN eat glow plugs if there is any alluminium residue it will destroy your plug
