Are the stock YJ one's so far off that they do not read accuratley enough that they need to be replaced. After all we are running 15+ year old rigs not Indy Cars. And like me your running a 4 cyl.
Are the existing ones not working, or is it more of a want than a need.
I can quit drinking anytime I want, but hey I'm no quitter :)
