Spark plugs?

I'm at 110,000 miles on my 03 WJ. I'm looking for recommendations on sparks plugs and where the best place is to get them from. Also the same questions for fuel filters. All help is appreciated

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.

Re: Spark plugs?

I have used Champion plugs in the past, but the last plugs I tried were actually some Motorcraft plugs for a ford. Seemed to run pretty good with them.

I have always liked NGK plugs, They seem to be good plugs regardless of the application.

Platinum. My mechanic had the fuel filter in stock so not sure what it was. But I trust him implicitly as he know how much I love my Jeep. He's a 4 wheel guy too.
