Ngk R6725
anyone run these spark plugs? they are single electrode oppose to the 4 flat electrode of the stock NGK.
I think they will be better due to the precision of the single electrode but from what I've read on a few japanese owner's page (couldn't find any pages of owners un the US) and the problem seem to be that the electrode wears off after about 4k miles. anyone used these? what are your opinions on them?

These are the racing version of the NGK line of plugs for the Rx-7. The electrode is the pin in the center and should not be a problem as far as wearing out in 4K miles. It will wear out but not that fast. As far as being better It depends on your application. I recently tested the HKS racing plugs in my car for my web site and found that when they say racing that's what they are for. If you use these I suggest only using them for the application that they are intended, racing. If you want more info check out my site or e-mail me.
