Don't Use in a 1.6L Ecoboost Ford Motor

NGK® - Laser Platinum™ Spark Plug

Put these in a 2014 Escape with 127k mi and immediately had misfires and drive ability issues after I did the valve cover gasket. Ended up putting the old plugs back in and car drove just fine. Too high of a performance plug for this specific application.

After Install

NGK® 4998 - Laser Platinum™ Spark Plug

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

NGK® 4998 - Laser Platinum™ Spark Plug

After looking on the computer for a good price on NGK 4998 plugs for the Jeep I found CARiD 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.

General CARiD Review

Spark Plugs, Air/Cabin Filters, etc. This is the best price for this platinum spark plug that I've found in my search. I have a Toyota Matrix and this was recommended for my vehicle from Toyota Parts Department, but the price was nearly doubled that of CARiD 's. In addition, I've ordered other parts from this company and have found their quality, selection, price are the best that I've come across. The times that I needed to speak to a representative was always pleasant, they are highly knowledgeable, courteous, helpful and professional. The website is extremely user friendly and is 'car specific' so that one can view any item that is custom to their specific vehicle and quick delivery too! That's why I keep coming back to this company and I highly recommended it to friends and family as well. RBA, Brooklyn, NY.
