Hello again. Posted a thread recently on my high oil consumption, which, thanks to many ideas and suggestion here, lead me to check my spark plugs (I'm a real rookie at this stuff and did not think to do so before). They are definitely in need of change, with the top one in particular being fouled. Apologize in advance if this topic has been covered many times, but did not find a thread on it specifically. But is stock the way to go when replacing the spark plugs, or are there better options? I have a 2015 Icon, with the full throttle termi exhaust and a K&N airfilter and 24,000 km on the clock. Would these small mods necessitate a change from stock plugs to something else? Someone I spoke with suggested I might be running leaner than a stock Icon because of the mods, and I might want a different plug as a result. Does this make sense? Any suggestions?
