iridium plugs FX HO
Hey guys, i got a 2006 FX HO about a month ago and have been riding the hell out of it. When i first got it, it would only run about 30 mph. So i changed the plugs and holy hell it went fast, 63 on the stock speed o meter.
Now about a month after 20 hours i've put on it, it still goes fast but doesn't seem to goes as fast as it did when i first put new plugs it. I can just nearly hit 59 but never 60 anymore.
So i was wondering if anyone has try iridium plugs and how they did. I know they should last longer, but i wanted to see if anyone else noticed a improvement with them.
