E-3 plugs worth the money?

Not true. The failure rate of NGK is going through the roof right now. Search the web. It's out there. And then there are the knock offs that are having about a 95% failure rate. Guys are pissing away a bunch of time, effort and money only to find out they have a plug issue.

Never had a problem with them myself, and I have tried multitudes of other plugs and designs in auto, sport vehicles and marine applications.
The results was that the best functioning plug was always a regular plug without some marketing BS change in design or materials.
Of course this is not taking recent China garbage into account.
