Spark plug Selection

#1 Post by TheJaspMan »

Has anyone every run an NGK CR9EIX? That is the iridium plug. I have two standard NGK plugs and one iridium. I think I was given it by mistake. But NGK shows it is the next step up for the Cannondale. I was wondering if anyone else has ever used one.

I (indirectly) fouled my first plug and am going to change it tonight.

I believe that Harry Moto runs the iridium plugs and has never fouled one, he just takes them out and cleans them every now and then for prevention. He swears by em.
