They look like 2 pin DENSO motorbike coils as found on virtually all modern bikes (there all the same) from what I've found between manufacturers.

I used them on my engine about 6 years ago and they worked OK but I changed them for a different type in the end

They are Capacitor Discharge Ignition so will require an amplifier to work correctly

I got some Magnetti Marelli ones that are inductive for £45 each in the end
