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.
Usually....different cars require different gaps. The plugs don't come gapped for each specific car.Originally posted by GTS_TURBO_HUNGR
I thought they were already gapped fine from factory. I got IK22 on my GTS and i didnt gap them. Is this really necesary?
I think they are one step colder. At least one step maybe 2. I'm not sure what the GT is though.Originally posted by venomceli
I thought the gap for the gts was a step or 2 colder than the gt plugs so i got the gts sparkplugs for my gt... I dont know if thats true or not becasue when i looked at both they looked the same, but everything is running fine....
