Does the factory recommended plug have a number 10 written to the right of the code number, if so, placing B/BR8HS standard plugs factory gapped to 0.7 mm will need to be regapped to 1.0 mm (that's what 10 stands for) to perform as same plug with 10 ending . If no number to the right can use any of the 2 as both costs same. Check service manual just to be sure.
It's the same example as B/BR7HS-10 (1.0mm) and B/BR7HS) (0.7mm) factory gapped.
