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 MOTORCYCLEiD 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.

Fine Plugs
Hi I'm sure the plugs were fine. They are highly rated. I called in to cancel the order because the shipping dates promised and those reported latter by the shipping company were several days too late for my needs. The plugs came anyway a few days late but were unexpected. I had to send them back because my mechanic had already bought new plugs before mine came. Just a miscommunication. No ones fault I sent the plugs back to the shipping company in New Jersey this morning for a refund. Thanks for your return policy and great service and prices in the past.

Perfect Upgrade
I installed a stage one tune on my 2014 BMW 650i Xdrive coupe and the car was going into limp mode when I gave it 100% throttle with the stock plugs with about 50k miles on them. Upgraded to these NGKs and the car is running stronger than ever.
