Re: Plug and wire question
I haven't used any of the high voltage coils but the high performance spark plugs I've used. I didn't notice any noticeable gain in power or fuel consumption but it may be that the gain on this products is small and takes time.
Overall, from my experience, don't expect to notice a significant and immediate change.
