What spark plugs do you use for your R1?
I read a forum that iridium spark plugs are useless if I have a tune on the R1. Currently, I have a 3/4 exhaust (SC Project), stock air filter (will get HiFlo Filtro air filter soon), and 2WDW ECU flashed. Not sure which spark plugs to get.
Edit: Forgot to add that I did smog block off plates and eliminate servo/plugged O2 sensors.
