Spark Plug help

I purchased (6) NGK ZFR6F-11G 6987 spark plugs I saw people talk about on this site so I can change mine out, but does anyone know if these are pre-gapped for the 08 Jeep Liberty?

It might be close, but best bet is to check the gap. I think its a couple bucks.

Look at your car manual for certain mine is says 0.043in. or 1.09mm - always check the gap and I take it you are using copper plugs?
