It's listed on the under hood emissions sticker.

It should be .043".

 

The actual part, from everything I've ever been able to find (without actually taking mine out or calling a dealer), is an NGK ZFR5F11 plug.

 

The plug is copper and should be replaced every 30,000 miles.  You could replace it with platinum or iridium, but the engine may not perform as well.  The price difference is also negligible when you take into account that platinum and iridium could last 2 - 3x longer, but also cost 2 - 3x as much as copper.  Stick with copper.  3 auto manufacturers had input in building the 2.4L engine - I'd like to think that many engineers have somewhat of a clue as to what they're doing.  It's also a grand total of 10 bolts/nuts to remove (4 plugs, 4 ignition coils, 1 engine cover bolt, 1 negative battery terminal) for a change.  If it takes you more than 30 minutes, you did something wrong.

What is the torque on the plugs ?  So I’m a bit confused..should I stick with the original copper plugs or change to iridium?

Stick with OEM. Just tighten until tight. Don't overthink it.

I tried upgrading to iridium in my 2.4l.  It caused a hesetation and stumble problem when doing quick stop and go's  . The engine runs best with the stock plugs.
