I got some of those crazy premium Bosch spark plugs at Auto Zone. Made a huge difference in my WJ. I had around 70k at the time. Have since gone to regular old ones at the recommendation of a Jeep friend, but don't like them. Will be going back to those crazy tipped Bosch ones.
Just got my fuel filter replaced, not sure what kind. But within 8 hours of driving, I gained back mileage and am at 17.5 mpg. Expecting that to go higher this weekend with lots of highway miles.
