Great Investment!
I had one that had a bad core but TRUCKiD replaced it. I had some little more power and ran smoother. Gas lasted longer. My idling rpm was greater and had to normal out after it warmed up because it would jump at stop signs. Ended up burning out two of the ignition coils weeks later which I am having to order here if they get them all in stock. So buy ignition coils if changing to these so it's one job. Worth the investment.

Tune Up.
Definitely noticed a slight horsepower increase after installation. Throttle response improved as well.

It is worth the price. You're not gaining massive performance but also not losing anything whatsoever. They spark faster/longer and are much more durable than other spark plugs due to the ruthenium element involved. Longevity Is better than other plugs as well. Time will tell. The plugs are likely not pre-gapped to the OEM specs of your car. If so, make sure you use a proper tool/gauge. Do not use the old style disc gappers as they destroy the precious materials.

Not the Wrong Decision
I hope I have 1% improvement, but it isn't the noticeable improvement I hoped for. These should be worth the additional cost in total life at least.

Improved Gas Mileage and Performance
In less than 500 miles I was able to record 37+ mpg for 200 miles at 70 mph with three people in the car. Also, around town went from 29+ mpg to 32+ mpg. Acceleration is smoother.

After Install
I finely installed these NGK 4998 plugs and I guess I was right. I now have a misfire on number 6 code so am going to put back my Bosch 9661. It might be the plugs or might not but thats the only thing different about the Jeep. I will will let you know after I replace them

NGK 4998 Plugs
After looking on the computer for a good price on NGK 4998 plugs for the Jeep I found TRUCKiD which had a great price for them $6.75 ea. Every other web page was asking $10 to $15 ea, one site was selling them for $26.31 ea. Which really makes me wonder if these plugs are the real thing. Like the old saying goes if the deal is too good to be true it usually is not. So am really not in a big hurry to install these until I find out if these are real NGK 4998 or cheap knock offs that will destroy my motor.
