These coils produce up to 67% more voltage than stock coils. They also have a faster rise time and longer spark duration which provide quicker starting, an improved idle and crisper throttle response. Other features include a finned top which acts as a voltage dam to prevent arcing, carbon-tracking and “flashover”, as well as improved configurations to permit simple bolt-on installations.
