They should be fine, looks like the regular coil on the 24 valve engines, but there is no way I can tell you more from just a picture.

Measure the primary winding, should be 0.5-1.0 Ohm normally if they don't have built-in igniters.

Start out with 2.0 ms and go from there, use 10A fuse.

yes this is  the same coil, ok thanks. I just get very weak spark, but it is on the table so I think it's because of weak power supply. thanks
