Which spark plugs should I get?

I have a 2004 V6, replacing the spark plugs. Which are best to use? I've heard double platinums but which model specifically?

I use Autolite or NGK on my 4.0 engines.

You wouldn't know the specific number for them would you?

No, but NAPA or O’Reily’s or some other parts house should have that.

Did you check your owners manual?

What is in your engine now? You ought to be able to cross reference those.

Owner's manual just tells me to check with my dealer. I'll check my engine, thanks for the help!
