Yeah, I just swapped in a new SR and it still has the old plugs in it. I was just curious as to which plugs I should get for the new engine. I bought a set of bosch plugs for my last SR, but I think I want to make a change.

NGK BKR6E, or BKR7E for a colder heat range plug.

6 is fine.

No Bosch, no platinums, just plain copper BKR6 ...
