Spark plug part # and gap

[Numan]

Can anyone tell me the correct spark plugs and gap for my 2003 RAM 2500 with 5.7 hemi

I conclude that your Ram is 4wd,

Here, https://www.autozone.com/external-engine/spark-plug/bosch-spark-plug/256756_10177_9868
The only iridium spark plug line engineered for both high performance and long life. The laser welded iridium tipped center and ground electrodes (Double iridium) provide exceptionally long life.
There are other brand companies to choose from, like NGK, Champion, Autolite, etc...Bosch is just one of them.

Should be a decal under the hood with that info. Raise the hood and look up for silver decal if it’s there. And use the champions copper ones!

I think stock back then would have been champion copper plugs. Usually not recommended to change from copper to the coated plugs but some people do. Copper won’t last as long but is the best conductor for electricity. Makes the change interval only 30,000 miles which can get pricey with 16 plugs to do. At least it’s easy! .044 on your gap.

DO NOT use anything but the Champion stock plugs. Gap is .044 or .045.

IF you get other plugs, they will run hot and run like crap.
