I like the NGK Iridium plugs. BR8EIX. They are about $10 retail but seem to be a good plug. I usually carry a BR8ES in my fanny pack for a spare. I've never had a problem with either plug or really notice a difference in performance from one to the other. I just figure the Iridium would be less prone to fouling. Plus it costs more so it has to be better, right?
I was chasing a weird misfire on my bike.
I had a box of new BR8ES plugs and kept swapping out the plugs without any correction to the misfire.
I then put a used BR8EG and the misfire went away.
