[Stay Focused]

I tried a search and came up empty. Here is my question:

I'm increasing the compression ratio on my Focus from stock to 10.5:1. This would suggest the temperature in the cylinder is going to raise. Do I need to go to the next cooler spark plug, or is stock still the way to go.

Thanks.

Bill Gude told me that I should go one range colder that stock. I'm going to do that today......Russell

So how do you pick such a thing?
Any Part #'s, or specs to look for?
