But if "answers need to be facts" and not just user opinions ..... that excludes or reduces the value of opinions. I guess I welcome all responses and I can sort them out as necessary.

As for as a company like Tower, as long as their bottom line looks good at the end of the year, I really doubt they care much what plug they sell for the DLE. The newer plugs currently being supplied seem to be an improvement so maybe they can get by.
