this is my current spark plugs are the NGK-Iridium IX BKR6EIX-11 <---- i have it for like 3months....show below all black.....my engine running pretty rich for stock...
my question is that number 11 represents the heat rang of the spark....11 is the coldest of all heat range....

my engine is pretty much stock just some bolt on CAI/h/e that is it....heat rang of 11 is not the way to go right....?

what heat rang do you guys suggest

 

NGK ZFR6F11
