What all do I need for replacing spark plugs?

[Nicholas]

The Bosch plugs come gapped already for the vehicle, so you don't have to worry about gapping the plugs. I was not aware of the issues with Bosch plugs, but I am new to the Jeep world. I already bought a set, but I may take them back.

I called the guys at a 4 wheel parts store and the head mechanic there has had them on his TJ for the past 6 years without a single problem, he said he’s never heard other bad things from others that have had em either. Don’t let one mechanics opinion bring you down about em, just throw em in mine runs better since I’ve just replaced mine

No.1 Most important, change 1 plug @ a time or risk cable Tangle Tango

I am not sure if the following information that I was told is correct, but I was told that you can/should only go up one (maybe it was two) steps in spark plugs technology. If the original plugs were copper, you could go up to platinum, but not double platinum or iridium. Not sure if this information was legit or not.

I just installed a set of Bosch Platinum plugs in mine. We'll see how they do. I noticed some corrosion on the wires, so I will be replacing them shortly. I'm not sure if I want to bother with the distributor or not.

I only ever replace one at a time. I guess if you work on the same types of vehicles every day you'll know which wires go to which plugs.

I've run Bosch Platinums for years in about everything I drive. But, it's good to know that there have been problems with them in TJs. Autolite is a darn good plug too and will be what I change to. I tend to stay away from AC as I've never had much luck with them in anything.
