NGK makes them and Nology makes Silverstone non-resistor (without a suppressor resistor). They have info at

page 4, and 24,25. It's a big pdf document

What I wanted to know is would I be at risk of blowing a coil. Since we dont have any high voltage resistor wires, our spark plugs are the only source of resistance for the coil. With these coil's haveing no resistance (silver center conductor w/no supressor resistor) would I be at risk of drawing too much current.

I thought about RF interference and I'm still willing to try them b/c the plug is pretty well sheilded b/c of the way nissan has them set up, so deep in the head.

These plugs are for performance in mind, unlike platinum plugs, which are for there durability and longevity.

I faxed them for pricing info and a question about our direct distributorless ignition system.
