Which 1.8 dx k jet coil Is best

i need a coil for a kjet 1.8 dx engine code, what is the best to get?

genuine bosch is all you need.

Brill thanks. I have a cheap shiny one on At the moment which I think is why I have no spark, do you have a part number so I can get the right one 

just pop into your local gsf branch, they should be able to sell you the right coil

note you may need to change the dizzy cap, rotor arm and leads to match the coil if its been messed about with in the past. you have 2 styles early which has like a set of wings on the lead ends that contact the outside of the dizzy/coil hole. then the late style which have a pin inside the dizzy/coil hole and a smaller hole with clip on the lead end that pops onto it
