Difference between glowplugs?

[ohmygahitscoby]

I went to my local hobby store and was trying to buy a glowplug. They asked me if my engine was turbo or non turbo. I told them non turbo, and they gave me a glowplug. I compared it with the one I already had, and the bottom shape was different, it was curved, the new one was straight. Does that mean my engine is a turbo and I should get the glowplug for the turbo?

Turbo:

Not turbo:

Which does yours look like?

What engine? Plugs also differ in temp and length.

I have the turbo one. I have a NovaRossi, I'm not sure what number. I can't find it on the internet.

What engine specifically? Others may have that engine and can help you.

Does the old plug have markings on it? They usually have numbers/mfr logo to tell the difference between plugs. Like the images. The turbo is an O'donnel 97, the other two are OS A3 and LC3 (the lc3 is on the other side apparently).
