NGK® Ignition Reviews

So far no issues after replacing the OEM plugs in my car with these. MPG has seen an improvement and the car picks up really fast. Glad I put new breaks on since I am going to need them now. :)

Well engineered and manufactured.

I bought this set about a year and a half ago and there work very well. There is always a consistent spark, the fitment was perfect, the cables were labeled for easy installation, and the blue color made the underside of the hood look more interesting. NGK always makes some of the best products in automotive ignition. Always my #1 choice!

Product was easily installed, no issues. Service was great and my savings was more than I expected.

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.

Along with the ignition Coils I also installed a set of Ceramic painted headers. Then made a 4000 mile trip and my 2002 Ford F250 gave me an average 46% improved gas mileage from 10 mpg to 14.5-7 mpg and now runs like a scalded dog. Thank You

No complaints.

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.

Great stuff.

Had cylinder 2 misfire for 2weeks.. Ran horrible. Had to change out the boots.. These fit perfectly. So I got 2. I'll prob just end up buying 4 more when they all act up. But this works!!!! They are very clean, well packaged. One package was open but I suppose the mail service did that. But thanks carid... You saved my butt.. Now I just need to fix the trans fluid leak and I'll be good!

The best spark plugs! They're most reliable.
