I was wondering if anyone here have used these NGK wire connectors to add wire to coils that have been cut short? I've a bunch of coils that came in cut back short, just sitting on a shelf. I see dime city cycles has these connectors, where you cut back the old wire an inch or so away from the coil and just add these connectors and new wire for $8.95 each. almost sounds too easy to work well, but it is NGK, has anyone else tried these?
