I am confused witch spark plugs to use on my particular car(ADR)
I have purchased Bosch FR6DC+ but the set in the care are NGK BKUR6ET 10 then consulting my manual that says Bosch FR7 LD+ or F7 LTCR the last ones hav three prongs on but the first one only has one? But when I orderd them it said they would be fine for my model?
When manufacturers specify a certain spark plug grade, you need to follow it to get optimum results. Whatever brand you use is ok as long as they are of the same rating which obviously the new Bosch is not as per recommendations.
