Answer
There are a few things I would like to point out in reference to this plug.
1. If it delivers a longer spark, why?
2. If it delivers a stronger spark, wouldnt this cause the coil pack to work harder and longer?
Everyone has their oppinions, and I know mine doesnt account for much, but I won't use anything thats not been tested for at least two years.
Thank you very much for enlighting me on this plug. This is considered to be a multi fire plug.
