Different markets, different fuels, different spark plugs.
Down here, no Ethanol, I have run NGK BP6EFS forever in the HE engines, no issues.
HOWEVER, NGK now have a new (well for some years now) spark plugs with a "V" groove centre electrode, and that part # on the box in my stash is BP6EF. The "S" in the first part # designated the centre electrode as "standard", and is simply a straight cut electrode.
Getting hard to find now as the "R" (Resistor type) are slowly taking over. The newer cars with COP must use resistor sparkers.
