re. use the f5dpor's? Or +4's?

[Ben Swann]

I'd be interested inthe results.  Again, I've been fine with the 4
electrode platinum, but maybe could do better.  The plugs have outlasted
the new fuel injectors I put in lss than 2 years years ago, but that is a
different story.

I will probably switch back to the 3 electrode plugs, as I definately have
had no problem with them, and I am certain they work better than single
electrode plugs.
