    The Title Looks Good
    The spark plugs are the same as the original ones and work great. It is nice to get the proper parts without any problems.

    These Plugs Work As They Are Supposed To
    I installed all 8 NGK G-power plugs and that gave me improvement of mpg ratio for almost 2 liters! That impressed me a lot. Will order them next time too.

    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.

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