I saw this thread and thought i could put an entry in the wiki for these plugs and i guess for other non standard plugs which claim higher fuel efficiency.

I dont know too much about the subject so i am posting to ask what people think about this mod.
so for anyone that has tried this mod
- does it noticeably reduce fuel economy
- is it a hoax, do you get no improvement
- is any improvement so small that we dont know if it works or not
- does it noticeably increase fuel economy

depending on what people think i can put this in any of the following wiki sections
- proven
- suggested mods (untested/unprovable mods)
- hoax products
