Yeah I have the same question but for a GT-S. Smaay, I remember you mentioning your recommendation a while ago. What do you suggest for a GT-S? I have 2-steps colder iridium plugs. Thanks.

I thought they were already gapped fine from factory. I got IK22 on my GTS and i didnt gap them. Is this really necesary?

Usually....different cars require different gaps. The plugs don't come gapped for each specific car.

I think they are one step colder. At least one step maybe 2. I'm not sure what the GT is though.
