What are people using these days? I usually buy whatever the local guy has in stock. I looked on Rock Auto. They have several brands now. Anyone have a preference or found "better" spark with some?

Does "always" include a CJ5 or specific to a GEMS (or any other OBD-2 close-loop fuel-injected vehicle)?But, I've always found an improvement in mileage and performance with higher output coils.
OK, on one project (a '95 R.R.C. Lwb) I was able to squeeze out on average about 20mpg on a vacation trip. Granted there were several modifications to allow this to happen.
Nick,If you could post a more detailed description of what you did it would be an interesting addition to the tech page here. I recently bought a 1993 SWB and it gets 12mpg if I'm lucky. Some of this is probably due to the sad state of neglect in which the previous owner kept it, so I hope things improve as I perform long overdue routine maintenance tasks. The RRC is a more comfortable vehicle than my D1 for longer trips, so an increase to even 16mpg would be a welcome change.
