What spark plug is OEM?

[kevcules]

2006 jeep liberty with the 3.7 litre V6.

Can someone please tell me what my fathers jeep takes for the OEM plugs? I want him to bring it over to me soon and we'll check what it has now, but I wanted to put the right plugs back in it. I'm considering the NGK Gpower copper plug but again, what did the engine come with?

thanks

Kevin
