PROPER SPARK PLUGS GAPPING

[isaiasp11]

HELLO I GOT AN 05 RAM HEMI 1500 AND I JUST BOUGHT 16 BRAND NEW SPARKPLUGS (CHAMPION #570 RE14MCC4) FOR MY TRUCK AND I WAS WONDERING ABOUT THE CORRECT GAP FOR IT, IM NOT SO MODDED JUST A K&N CAI AND MID LENGHT PACESSETER HEADERS RUNNING ON 91 OCTANE TUNE

Are those plugs copper core? Its .045". If they aren't copper core, don't bother, because you're just gonna have to change them again when the truck starts shutting itself down randomly.
