You are fine with youre NGKs. If you want you can go a little bit hotter because it will ignite your air fuel mixture a little bit better. Don't go too hott because the motor might not be able to dissipate the heat fast enough equallying to a meltdown. I've seen it plenty of times and everytime it happened they had Bosche Platinum Plugs in it. DO NOT USE BOSCHE PLUGS!!! They are very hot but being apart from hot they are very concentrated. They create hot spots in the motor and unless you have a VW bettle that the manufacturer calls for Bosche platinums, don't put em in your car. I've been working at the same shop for 10 years now and I get atleast 10 headgasket or motor jobs in per month beacause the local parts store sells the good NEW AND IMPROVED - BOSCHE PLATINUM PLUGS!
