Cold spark plug recommendations? Duratec 2.0
Looking for some recommendations for a new set of colder spark plugs for the Focus. I’m still running into some overheating problems with plugs, due to my lean fuel / air mixture and heavy foot. Trying to find some colder plugs that still preferably have an excellent life. Any help would be appreciated. Currently using NGK Iridium plugs.

I’m running NGK Laser Iridium Plugs myself, so I couldn’t possibly recommend anything else.
NGK makes top quality spark plugs, only brand I’ve used in both of my cars.
Here’s my last NGK Iridium plug. Are the Laser any better?
