colder plugs have higher numbes. I use heat range 7 plugs in my car, which is two steps colder then stock. I know I have a KA, but the same thing applies. You should be just fine with BKR7[anything] plugs gapped to .030" If you are not running much boost or something and you are having problems with the heat range 7 plugs fouling, then go to heat range 6 and a gap of about .035" should be good.
