First of all are they a direct swap for a standard 3 door coil as they look noting the same?

Second what are the benefits of upgrading to this?? Bigger/Better spark etc etc?
what about plug gaps after fitting one?

Cheers

 

You need to cut off your standard loom plugs and use spade terminals onto the coil

 

You can instead buy some bullet terminals to plug into your existing loom wires and then make up 2 short leads with spade terminals on the end to fit the group a, a slightly more powerful coil, the std cossie coil is crap power wise, use a group a with a some IK27, or AGPR12PP8 plugs and you will notice quite a difference in smoothness(and idle) and low down pull will be better as well, well worth doing imo when I did it.
Make sure you get the + and - right, the markings on the group a coil are buried between the two parallel terminals each side.
