Denso Vs NGK – Which Spark Plug Is The Better Choice?

Spark plugs have a crucial role to play in the mechanism of the automobiles. A car needs good-quality and fully-functioning plugs for ru...

Before diving deep into the discussion of Denso vs NGK, you should know their type and specific features to see if they fit your need.
Both the types are iridium spark plugs. The metal is much less conductive than copper but lasts longer and work at a low temperature. It is also 4-5 times costlier than platinum.

Both are iridium spark plugs and have a long lifespan.

Iridium spark plugs are not the best in terms of performance but nothing can beat their longevity. When a copper plug lasts for around 20,000 miles, the average lifespan of an iridium plug is 40,000 – 60,000 miles.
On the other hand, they are also a better option than platinum plugs in terms of consistency and longevity. Unlike the platinum models, they are stable, don’t grow gap over time, and don’t create extra stress on the ignition system. They also need less maintenance as checking their condition at every 3 to 6 months is enough.
In a word, iridium spark plugs last longer than other types and their performance is better than the platinum units.

Denso vs NGK Plug: Which One Is Better?

It is hard to pull out a winner in the NGK vs Denso debate since both are iridium spark plugs and offer almost similar performance.
Denso plugs are installed on almost every automobile model manufactured in Japan. The iridium used in them has a superior hardness. The electrode’s diameter in these plugs shrinks more than an NGK. For this reason, Denso plugs won’t last longer than NGK units but they will be better at producing powerful sparks.

NGK plugs are cheaper and lasts longer.

On the other hand, NGK plugs will be a standard replacement for their platinum alternatives. They require less maintenance and provide a more stable and consistent performance than a Denso.

Conclusion

With the passage of time, spark plugs have been developed into a much more heavy duty component. Both Denso and NGK plugs work well with all types of vehicles – from light cars to heavy-duty pickup trucks. In this choice between Denso vs NGK, you will choose the first one if you care about the horsepower of your vehicle. It is only a fraction of a percent of the increase of power, though. But, NGK should be your choice if want a stable, long-lasting performance at a lower cost.
