I have an '03 America (VIN SMT905JN02J150218)
My bike has 34k on the odometer and still has all the stock ignition components.
I was in a NY dealership last week (Destiny Motorsports) and the owner suggested I'd get a noticable performance pop from Nology coils.
Given I haven't experienced any issues, would upgrading to the coils and this CDI unit be a good move. At some point, my stock components have to fail.
