i know yoda on here was really backing these spark plugs up...saying they were better for nitrous than copper...i want to know if any one else has any thoughts on these vs. some ngk v-powers or somethin...thanks

I just found this, since I'm getting paid to do absolutely nothing, and am going through old posts..
These, and Beru (Now Ractive, I think) are used by serious racers, because they do work, but not for very long.
Here's how it works: The less dense the electrode material, the faster the current can travel through it. However, it wears down more quickly, too. Also, They are about $9 a piece. If you want a little more performance, and are willing to pay for it, they do work. They will improve your gas mileage, too. I'm thinking about getting a set for race days.

Brisk are well known here in Portugal, but for french cars ...
I am very happy with my Denso Iridium plugs, and they did improve my mpg
