Product advantages: high current efficiency (chlorine evolution or oxygen evolution environment), excellent corrosion resistance, long electrode service life, electrode size can be designed according to user requirements, electrode substrate can be reused many times, no pollution to the medium.Īpplication: Chlor-alkali industry, sodium hypochlorite industry, sewage treatment industry, freshwater disinfectionĢ. That would be a situation where a colder plug could help, but it wasn't clear if they did any sort of test with a colder Iridium.The advantages and applications of various titanium anode plates: ruthenium titanium anode plate, ruthenium iridium titanium anode plate, tantalum iridium titanium anode plate, iridium tin titanium anode plate. If you drop the octane, the risk of knock will go up. The Premium Fuel in our cars, for example, is specifically to avoid knock. Yes, the specific use case was for people that couldn't get better than 91. With the FI cars, there could be some benefit from the Ruthenium plugs as they don't tend to last as long. So with a stock NA car, I doubt there is much benefit as Iridium spark plugs are already good for 100k miles or so, and there are concerns with spark plugs fusing with the aluminum heads if the spark plugs are left in for too long. Yeah, I wouldn't try them unless I am due for a spark plug change anyway. They quote a 0.2 second advantage with Ruthenium over Iridium over a period of 23 seconds, so with our cars that can do 0-60 in mid to low 4 seconds, the ambient temperature can probably cause more fluctuation than Ruthenium spark plugs ever could. With the FI cars, there could be some benefit from the Ruthenium plugs as they don't tend to last as long(I think the FI Camaro's need spark plugs at 60k miles instead of 100k miles).Įven on the NGK website, the performance difference between Iridium and Ruthenium is very small. It seems like most people online who notice a difference are either due for a spark plug change anyway(so even new Iridium spark plugs could also have made the same improvements), or are turbocharged(which are harsher on the spark plugs to start with). That, and the Fiesta ST seem to be the only cases where they saw a gain in power, or rather, a conservation in the original power as those cars don't pull timing as much.Īlso, wouldn't run colder plugs on a stock or mildly modded car if you are daily driving it. I think they tested the Californian 91 fuel with the Ruthenium spark plugs of the same heat range as the Iridium plugs, but yeah the post isn't 100% clear on that. Since a colder plug removes heat more quickly and reduces pre-det / knock, it would seem that colder Iridium would garner identical results and at a lower cost than the Ruthenium. What I -didn't- see anything about is whether they also tested one step colder Iridium plugs in the same situation. They did test Ruthenium plugs that were one step colder in terms of when they ignite and showed that it did reduce knock in lower octane fuels.
They basically said that the Ruthenium and Iridium plugs run the same.
