I have a 96 XJ with 192k on the clock. I know with some average care the engine will easily do 300k. Are there any people here that have more than 300k and it just keeps going? Lets hear your mileage!
Champion RC12PEC5. Like the O2 sensor, the brand actually matters here.
I have used Champions in mine for years. First the SUV & truck plugs and when they discontinued them whatever NAPA said to use. I really don't find the 4.0L very sensitive to particular Champion plugs, but I haven't tried Autolite, etc. to compare. I've always just used the Champions and the 4.0's run fine.
