Coils- Zxr250

Hi guys,
Has anyone ever attempted to replace coils? (I'm assuming I have the correct technical name for them
)
I'm not too sure if the boyfriend (who is a Mechanic) will know what he's doing. Maybe I'm better off booking it in to get done at a Kawasaki dealer?
I have been quoted $99 (each) for a used one or $182 for new
Any advice would be greatly appreciated
Cheers,
Loz
