I wouldn't worry about the green tinge... probably some byproduct of an additive in the gas.

Overall, now, that looks pretty decent.

Thanks Krewat. I have a new set, one hat range cooler coming today. Probably new wires too, the terminal pulled out of one last night on the side of the freeway trying to get these pics.

Yeah, the original pics you posted were probably mostly "cruise" and high RPM with low load... It's hard to say what temp range a plug needs to be these days, with 10% ethanol and detergents and other additives, along with playing around with compression ratios and aftermarket intake/carb setups.

Run the colder plug for a few trips, and see what they look like. If they start to look really dark, well, that might not be the solution
