Do you have a favorite for warmer weather versus colder weather? I seem to have more luck going to Motorcraft in the Summer and Champion W16 in the Winter.

No, but that's a good point. Anything that affects the temperature of the engine affects the temperature of the spark plugs whether it's the outside temperature, low on water, high speed .... just anything.

I've found that the W-16Y has been a good, all the time plug.
