Smile 2009 Jeep Wrangler Rubicon Best Spark Plug

Gents, I know this question has probably been asked hundreds of times before as Im new to the Jeep Forum I thought I would risk asking it again. SO here goes: I have a 09 Jeep Wrangler Rubicon with ~80K miles I bought the jeep used so what records I have on it dont indicate if the spark plugs have ever been changed so I figure with ~80K miles on the engine I should just change them.. So for the umteenth time what would be the best replacement spark plug to put back into my Rubicon.. Thanks!

How did you manage to get to the rearmost passenger side plug? You didn't use a U-joint by any chance?

I had a local shop do it. I'm not sure. I had a laundry list of stuff to be taken care of , so I'm not sure how they did.

In case anyone looks into this thread, the problem turned out to be way overblown on websites and forums. I used the 3/8 U-joint and it was easy. The worst part was to make sure that debris do not get into the engine through plug holes.
