I know my gap should be .040 according to the internet but under the hood, the factory sticker says 1.020. That CAN'T be right. I'm going to go with .040 but does anyone know why the factory sticker says 1.020 and should I ignore it as planned?

Also, Any tips from anyone who gapped their 4.7 differently and noticed better fuel or performance?

I appreciate any replies. New member and first post.
