Yes. And spark plugs will NOT affect your engine operating temp. Something else is wrong.

Running temp isn't 210. 210 is when the aux fan kicks on and that is why its in the middle of the gauge. Running temp should be about 190.

If you can see your fuel gauge dropping you have another issue. (Like a hole in the tank) And like said above the plugs are not the reason for your engine temp issue.

It really isn't that serious. I am using more gas than normal, but I am going to run a full tank through it and see what happens. A full tank with my type of driving usually lasts me around 250 miles or so. Give or take. It has been around 90 degrees down here, but when this cold front came through it dropped temps into the 70's. Could be my temp difference. I won't shoot them down yet. It runs quite smooth with them in. For $2.39 I shouldn't complain. I did have the Bosch Fusions in there..With the exception of the one Autolite Platinum...???? They were in it for a long time. Way before I got it. I will fill the tank up and drive it like I do everyday and see how mileage looks then get back to you guys.

Copper NGK is the way to go in a 00 or 01 (copper Champions in 87-99). You shouldn't necessarily be hitting 210, and plugs wouldn't be a reason for temp issues anyway. Plugs also wouldn't be making you guzzle gas.

Did you check the gap on each plug before installing them ?

NGK ZFR5n's gapped to .035 using a wire gaping tool. I'm going to fill it up and see how many miles I get out of a tank of gas and compare. It runs very smooth, but it used to get to 210 and stay in the 200-210 range. It could be the temperature drop from 90's to 70 degrees outside. Like I said I'll run it for awhile then compare. It had the Bosch Platinum Fusion plugs in it. As far as idle and start up its perfect. Driving feels perfect. I'm going to watch those numbers and not get my revs above 2250 rpms and see what happens.

A lot of people don't believe it but these Jeeps truly run better on the standard plugs. The 96ish and under use the champions and the 97 and up use the factory NGK plug.

I'm going to see how she does. Wish I could win the lotto so I could buy a lift and some new rims and tires for her. Ha Ha!

Join the club. I need a lotto win just to do some rust repairs and other restorations. Buying toys like lifts and wheels is WAY in the future for me unless I find an insanely good deal.

Prices look about the same as rage but the Curt one looks better just going by the pictures. Let us know what you think when you actually get your hands on it. it

Should be here tomorrow! I also think I have this gas situation figured out! Think it was cheap gas. Put name brand gas in it and it seems like it has done better. I still ordered Bosch IR Fusion plugs like what it had in it. They ran good so I'll go back with them. Yes they are 40 dollars for 6 on amazon.com, but they have a mail in rebate of 4 dollars a plug. $16 dollars total for Bosch Platinum IR Fusions isn't bad.
