Overview

In all the years of being an Auto Mechanic, one of the 1st car components I came in contact with was Spark Plugs.

I wanted to learn all there was to learn about this amazing component that performs such a vital role in an Internal Combustion engine.

In those early years I must admit, That NGK was not the brand we used. As time passed the good brand that we used was no longer available to us.

Enter NGK, when I 1st worked with NGK Spark plugs I was very biased and had nothing good to say about it.

As time progressed I decided to really test NGK Spark Plugs to show its weaknesses, try as I did, I could not get these damn NGK Spark Plugs to fail.

Finally one day, after fitting a set on an old Ford Cortina, my colleague came to me and said, “Hey, finally, what you have been looking for”, the car was running bad and misfiring.

To my disappointment, upon checking the cause, I found that my colleague did not check the gap setting, as the plug must have been dropped prior to fitting.

Comparatively, NGK Spark Plugs started to perform better and better as it not only matched, but out performed the brand I became accustomed to. I am using NGK Spark Plugs since.

We had an approx. 5% fault rate with the previously used brands, but with NGK, we never had a come back, then I started to sit up and take notice.

We all know how sceptical we as humans can be about the unknown, or the new kid on the block.

Well with so much water under the bridge, about 20 or so years worth, NGK is still my 1st choice and beloved brand of Spark Plug.

My Personal Experience with NGK Spark Plugs

I have many, stories to tell of NGK Spark Plugs, one has just come to mind,

Long life Plugs

Long life Plugs

I was testing a Ford Ranger 2.5L petrol for breakdown of the power, at speeds over 80Km/h, I checked the fuel system, exhaust system and air intake system, all clear, so I started testing on the ignition system.

I decided to fit a set of ILTR6A-13G Laser Iridium Spark Plugs and see if it cleared the problem, hell yeah, this Ford Ranger never rode this well in all my  testing and component changes thus far.

Diagnostics

But here is the kicker, when I ran diagnostics on the ignition system, using my Maxisys MS908 Pro, I found a coil pack fault code, after replacing the coil pack and clearing the fault code, damn, this vehicle performed at it’s peak.

The point here is, even with a faulty coil pack, the ILTR6A-13G Spark Plugs, made an enormous difference compared to the make of plug I found in the Ranger when it came to me 1st, it broke down under load.

This cemented my confidence in NGK Spark Plugs.


Final Opinion

With it’s

  • superior manufactured quality
  • performance under load conditions
  • huge choice and range of applications, including, racing
  • the intro of Iridium Spark Plugs for longer replacement intervals is a huge plus

One has to walk a long distance to find a worthy replacement. NGK is my number 1 choice of Spark Plug.

    Wow!!! The first thing that really caught my attention is when you said in your review “We had an approx. 5% fault rate with the previously used brands, but with NGK, we never had a come back, then I started to sit up and take notice.” That is absolutely amazing. especially for a spark plug that is not made in the US or Germany. This has definitely caught my attention. The next time I change the plugs on my vehicles, I will surely be trying the NGK brand for myself.

    Thank you for this great review Gary,

    Wow! I can definitely tell you know your stuff! I’m coming back here for all my car related issues!
    Thanks for the advice and review of these spark plugs. (I honestly didn’t know there was that big of a difference between brands).

    If needed, could I replace a spark plug pretty easily (with the help of a YouTube video) or is it something I should outsource? Can it be dangerous in anyway to do it yourself?

    Thanks for the advice!
