my OS 91 FX came with an OS type #8 glowplug.

Kostas,
...Which is OK, with the low nitro fuels that you have in Greece.
OS does not limit the #8 glow plug to smaller displacement engines, but still, if OS says the A5 is better for the .91FX, should I need a replacement, I would opt for it and not for the #8.
The A5 should cost a bit less too, compared to the #8.
