Hi guys, i want to do some small mods to my VN but not looking to spend thousands on it yet.
So im now looking to get some new spark plugs, coils and leads.
I was checking out what they got on ebay and came across this thing.

PROCOMP BLUE hi intensity ignition coil. - eBay Ignition Systems, Ignition, Charging, Car Parts, Accessories, Cars, Bikes, Boats. (end time 28-Apr-09 10:25:27 AEST)

Hopeing you guys can tell me how it works and if its any good.

Thanks Terry

Just a hi voltage after market fancy looking coil by the looks of it. ATM its at an ok price if you needed a new coil, but mostly they not worth much of a gain if any, as at best it gives you a slightly hotter spark which is barly any benifit.
