Im about to swap my plugs out. Does anyone know the proper spark gap for the 5.7?

Using the OEM replacements FYI.

OEM calls for .040"

Thank you sir. Are you sure thats for the 4th gens? I should say a 2012 specifically. I have been looking online, and seeing a bunch of different gaps for the same engines. Guessing its due to the other parts of the ignition system. Coils and whatnot. Just wanna make sure.

For a 2012 hemi using OE plugs, gap is 0.043"

Ok, thank you folks. Bummed cause I think those plugs come gapped at .044 out of the box. Sooo close.

Swappin em in the mid morning tomorrow.
