Spark Plug Reccomendations

[Black Moon]

I tried the search with little results so can someone suggest a plug for an 03. Only mods are headers, no cats, Mopar exhaust, cold air, 170 stat and SCT tune. I would appreciate to hear what is most commonly used.
Thanks

I personally like iridium plugs for NA motors. I use Bosch 4508 in my '06 Coupe. They work like a champ.

My mods are similar to yours.

I also love the Iridium plugs. A little pricey, but they seem to smooth out the overall RPM's.

Stay stock, anything else is a waist of money.
