Just be sure to get the "NTK" brand ones. They are the original ones in the jeep. There is also Bosch but they may take too long to heat up and trip the cel on your dash

I would do plugs and stick to stock plugs when you do. Jeep's are sensitive to what type of plug you use.

The 3.7 isn't as sensitive to plug type as say the hemi or a gen 2 4.7. I actually get better performance from the autolite iridium plugs then I did on the stock copper plugs. However that said I would stay away from Bosch platinum plugs. It doesn't seem to like those well

But yes, I would do plugs too on top of the o2's
