    Iridium, it does make a difference....

    There is a lot of voodoo science around when it comes to spark plugs. You try to "read" plugs but on specialty set-ups like my supercharged rotary motor a lot of that goes out the window because these engines run richer to begin with and you literally have to "catch them in the act" coming right off cruise or in-town driving which is pretty dicey with traffic. Best advice? Buy a good quality AFR gauge set-up with a Bosch sensor. Being able to see your air/fuel ratios instantly will show you how minor changes can shift economy, power, etc. As opposed to the copper plugs I had always used these plugs definitely are allowing a hotter burn so I could subsequently richen everything from idle to full tilt flat pedal. Noticeable power increase and even picked up about a mile per gallon. ...

    Wow!

    Just put this spark plug in a 1999 KX-125. It literally feels like it has twice the horsepower it had before. The low end torque feels like it has doubled also. Highly recommend!!!!
