Just wanted to 'hopefully' clear this up. From what I remember, heat range '5' is stock. And some people use the '6' for mild builds. But then the highest/coldest I've seen is a '7'. Which is what I use.
Anyone else want to confirm this? This is all for the KA motor, right? Because I've seen them go up to heat range '9' for the RB's, but not the KA's.
5 is like bone stock when modding your engine your never going to hear someone talking about useing NGK 5's like for turbo and stuff.
