Also are these the best plugs for the classic?

I am of the idea that the best spark plug is the original one recommended by the manufacturer as long as the engine is completely original. I put the NGK BKR7EIX which are a colder because of the modifications I have. In any case, it is not very clear to me if the 1.1 mm iridium GAP should be reduced when they are placed in a turbocharged engine since in the subaru turbocharged engine the GAP is 0.7 mm.
