    what are the best plugs to use in an SJ engine? do they depend on mods etc?

    Unless your highly modified run 7 series plugs for surf riding. Thereafter it depends on your head setup. OEM heads - BR7HS. For aftermarket i.e. ADA etc - most of them run the ES version - BR7ES.

    Why the 7 and not the 8 for surf?
