FAQ: Any Improvement in Performance for using Iridium Spark Plug?
I think they add nothing more to performance than new and clean standard spark plugs. Experts also say little to none as far as power gains.
They might last longer since Iridium alloy spark plugs take longer to wear out.
What is Iridium in the First Place?
Iridium is a very hard and brittle metal [in the same family as the Platinum], is one of the rarest elements ever found on earth. It is the heaviest metal known to mankind beside Osmium and is the most corrosion-resistant metal even at 2000 °C. Annual production and consumption only three tonnes. As expensive as Gold but Iridium alloys [with Osmium and Ruthenium] can be up to five times more expensive!
Some scientists suggest that Iridium [first discovered in 1803] came down to the earth with the asteroids because it is found in meteorite fragments much higher than its average abundance in the Earths crust...
Why Iridium Spark Plug?
Iridium spark plugs wear out much slower due to its super strength against corrosion/oxidation/wear&tear at extreme temperatures and pressures in hell-like environment of the combustion chambers.
Nevertheless, it is a common misconception that Iridium spark plugs give more horse power and better fuel consumption. The truth is if the conventional spark plug is new and in good condition, we still can get best fuel consumption and maximum performance from the engine.
It doesnt matter which kind of spark plug we use as long as it is within the specifications. If freshly installed, there is no difference at all. But after more than 20,000km, the cheap or standard plugs give a little bit more fuel consumption and reduce power while the Iridium plugs are still as good as new....
... up to 200,000km for iridium spark plug with platinum ground-electrode[?]
What about "Multi-electrode" spark plugs?
This type of spark plugs produce only one spark on the smallest gap available. The wear is divided over multiple gaps so it stays "fresher" for a longer time. For instance, for a 4-electrode spark plug, it takes about 4 times longer for those to show the same wear as standard plugs.
This means that we can keep them 4 times longer or replace them in the normal interval and have a better spark in average. Again, it is another myth saying that multi-electrode spark plug gives higher performance.
I use 4-electrode plugs for a D-segment car and keep them twice as long. This generates the same costs for spare plugs but gives me a slightly better spark where standard ones would be seriously worn already.
The Truths?
Iridium and multi-electrode spark plug do not produce higher horse-power and give lower fuel consumption so to speak. They just maintain top performance longer than the conventional/standard spark plus. Thats all...
Conclusion?
As an analogy, it does not matter whether you use 18k-Gold Zippo Lighter or Mancis Cap Lada to light-up an Altadis’ Behike Cigar!
