how many run ngk 2668 will be doing these this season $$$!
existing results? comparisons?
been running ngk 7173 non resistor for 4 years but trying to track down some electrical noise / gremlins

I ran the -8 ngk copper and the TR8Ix back to back last year...no more power, but the ix's last longer on leaded fuel....enough for me to keep buying them since plug chaanges are not funnnnnnnn.
The Ix are iridium. I didn't think you could gap those? Or do you just run them straight out of the box?

R5724-8 is stock # 7317 non-resistor
TR8ix is 3691 resistor.
I've run the -8 copper non's with MSD's, Magnecor and Firecore without any RFI. Fine plug for .708 reach, taper seat, blah,blah,blah....and cheap...I just hate plug changes in a turbo car....TR8ix extends but adds zero power....but I'm lazy and will continue to use them.

gotcha, well they are in to try for friday, didnt get to take a trip around the block.
guy at ngk told me to get the non-resistors out of the car, hopefully he wasnt just selling me plugs.

You should never use a non-resistor plug in a modern efi equipped car. The resistors are there specifically to help reduce electrical noise.

resistor plugs arent any difference price wise than non.
In fact, I cant even remember the last time I seen a non resistor plug for sale here, or anyone even still using them
How is the noise or interference manifesting itself ?
