Yup, I got them. They are 9mm(I think NGK are 8mm) and they have a resistance that is similar or lower to the NGK wires. As long as the resistance is the same or lower than NGK, for example, you should be fine with them. I am running upgraded Jacob's ignition and was gonna go Jacob's wires but Jacob's are only 8mm and the Ractives had a slightly lower resistance. We compared them to my bro in laws Magnecor 8mm and there is a pretty big difference thickness wise.
If i am not mistaken, doesn't Ms. Vixen have the Ractive wires?
