Just curious as to what you know about these or what experiences you've had. P.S. I'm not under any delusions about making "free" hp through plugs, wires, etc.; Just wondered how these stack up against other plugs on the market.

 

they are alright, prefer ngk's though. No big deal about them

 

i use em. basicly its a hotter spark. results in slightly more complete combustion.

 

i have them, no problem with them...but like u probably know you really cant tell the difference one plug to another unless you have heavy mods
