I know alot has been written about this subject but I thought I would share my experience. The physical properties of ruthenium and the specialized electrode designs of the new plugs allows them to outlast current platinum and iridium plugs by a significant margin. Note that this is not you are guaranteeing failure, but increasing risk or creating risk where none otherwise existed before. In addition, simply keeping a sharp edge is not the only important thing. I get NKGs for my vw beetle and champion copper cores for my truck. NGK recommended against using platinum plugs with nitrous oxide injection because the platinum sometimes blew off, but that hadn't happened with iridium plugs. Compare Palladium vs Ruthenium of the Periodic Table on all their Facts, Electronic Configuration, Chemical, Physical, Atomic properties. Iridium IX® vs. OE Iridium Spark Plugs. Iridium IXÂ® plugs are an excellent upgrade from standard nickel plugs. However, the coating is a one-time thing. (We had to add that last part for good reason, sadly. I switch from the ngk iridium 1 step colder plugs that everyone uses, to the new ngk ruthenium 1 step colder plugs. Ruthenium element has been extracted from used nuclear fuel. If you have an issue with your vehicle someone here can probably help you. Ruthenium looks like is an experiment by Ngk, I would give ti some time before these plugs prove themselves reliable before buying. Ruthenium demand climbed 9 percent last year to 1.204 million ounces, its highest since 2006. Live PGM Prices.  Lastly choose the number of â¦ But Honda, which usually installs NGK or Denso plugs at the factory, said, for the Pilot: "Apply a small amount of antiseize compound to the plug threads, and screw the plugs into the cylinder head, finger-tight. NGK RUTHENIUM HXâ¢ ngksparkplugs.com Tech Support: (877) 473-6767 ext. Below is language from NGK's website on those two: NGK builds two types of iridium spark plugs: OE Iridium and Iridium IXÂ®. Live Spot Prices for PGMs in ounces, all in real-time in 40 currencies. Iridium element is known as the most corrosion resistance metal . Ruthenium element has been extracted from used nuclear fuel. The element Iridium was discovered by Smithson Tennant in year 1803 in France and United Kingdom. It all comes down to how long the electrodes hold a sharp edge and resist gap erosion. I could get the standard Iridium IX ($6.85) or spend more than double on the Laser Iridium ($14.73). So really, there's no such thing as a "performance" spark plug. Like most metals, finely divided iridium powder can be hazardous to handle, as it is an irritant and may ignite in air. Here's an article from the March, 2013 issue of Motor, a mechanic's journal, that quotes spark plug and auto manufacturers about their recommendations about anti-seize on spark plugs: https://www.motor.com/wp-content/uploads/Trouble-Shooter-March-2013.pdf. There are other factors why nickel spark plugs aren't really used in modern cars but you are right that the low durability (relative to precious metal spark plugs) is certainly one of the reasons. Have an answer or just a good tip? Current price of iridium - $1460 per troy ounce Current price of ruthenium - $263 per troy ounce Could NGK simply be using a cheaper metal, calling it the ânext new thingâ, charging more, and profiting handsomely as a result? Regarding copper spark plugs: there is a copper center electrode core in every spark plug, whether it's "copper" or precious metal. #Markvlogs #NGKVSDENSO #SPARKPLUGBATTLE #Hyundai #EonHi Guys!Welcome back to my Channel!GOOD DAY GUYS! So, a spark plug with a better center electrode material performs better by being more resistant to gap growth (higher durability). Share; Pin; Tweet âA spark plug is just a spark plugâ is a common, yet incorrect phrase. Iridium, tried and proven. Ë Ë shortens the life of traditional Iridium and Platinum spark plugs. However for its long-thread plugs it said: "New plugs should be installed using a thin-film coating of high-temperature nickel antiseize on the ground electrode shield. They are a great option for modified engines, and where recommended, are appropriate replacements for OEM spark plugs. So, I need spark plugs for my 2006 Miata. The Iridium IXÂ® plugs are offered in various heat ranges and sizes to fit most automotive and non-automotive applications. OEMs have stopped using them because they won't last through the warranty period. They don't list a Ruthenium HX part for the L15, so I found a model that has identical specs to the OEM ILZKAR8J8SY Si plug except the â¦ I always get the oem brand because that works the best for your car. My google fu skills pulled up no useful real-world info on Ruthenium plugs. Copper plugs actually perform better than precious metal plugs. Got a juicy car meme? While you're right that precious metal spark plugs have higher performance because they are more resistant to spark erosion and high temperature oxidation erosion, there is a difference between precious metals and the various alloys that are used. While you may call it a "weak" or "strong" spark, nickel spark plugs actually have a "weaker" spark because they have much lower ignitability due to the large amount of material around the center electrode that absorbs the heat of the flame kernel as it grows, thus slowing down the kernel growth rate. Experiments don't start in the market, nor are they done for aftermarket (when it comes to design changes like center electrode material). Copper has lower resistance than plantinum or irridium. If you remove the plugs and intend to reinstall them, then you must use anti-seize on the reinstall. "Copper" spark plugs are a bit of a misnomer these days. NGK builds two types of iridium spark plugs: OE Iridium and Iridium IX®. 3 H 2 O is most important because it is a good starting material for other compounds and reacts readily with olefins and phosphines. That said, there certainly can be more or less energy contained in a spark event, but that is more or less entirely controlled by the coil, not the spark plug. The nickel or zinc, depending on manufacturer, plating is designed to prevent corrosion and seizing. Ruthenium is a transition metal found in the middle of the periodic table. Not all plugs work in every car. Since they're pretty easy to change on a Miata, I'd go with copper. This is so incredibly wrong. Iridium spark plugs. Iridium is supposed to be good to 100000 like Duran said. When it comes to electrical resistance, the difference in resistance is completely negligible. This means thereâs an even greater reservoir of voltage at the coil if the cylinder requires it. All dual precious metal plugs are designed to provide maximum longevity. A related question is whether to apply anti-seize. Our Periodic Element comparison tool allows you to compare Periodic Elements properties side by side for all 118 elements | SchoolMyKids Interactive Dynamic Periodic Table, Periodic Table Element Comparison tool, Element Property trends We love those things. The nickel coating on the threads works every bit as good, if not better than anti-seize. Id stick with what the manufacturer recommends. It has 130,000 miles on it and I was wondering on which spark plug to get. Ruthenium derived its name from from Ruthenia, the New Latin name for Russia. The Iridium IX spark plugs are a single precious metal aftermarket performance plug. If you still want to use anti-seize you MUST reduce the settings on your torque wrench by 10-15% percent (can't remember if it's 10 or 15). It is used for producing chip resistors and contact. Car makers like platinum and irridium because they keep their sharp edge longer and resist gap erosion because those metals have a higher melting point. NGK was and still is very much against the use of anti-seize, saying its trivalent zinc chromate-plated plugs don't need it and that it causes plugs to be overtorqued. Yes, don't use anti-seize. Dyno test: Stock vs Granatelli Wires and NGK Iridium plugs We've got a 04 Neon SRT-4 that we are using for a Donor car for our SRT4 drivetrain swap into our 95 Neon. DO NOT coat the ground strap. ), Looks like you're using new Reddit on an old browser. They also have the Denso Iridium spark plugs ($9.76). Simply select a metal and a unit to display the price. Iridium derived its name derived its name from from Iris, the Greek goddess of the rainbow. For the OE Iridium series, dual precious metal means iridium on the center tip and platinum on the ground electrode. All dual precious metal plugs are designed to provide maximum longevity. Every 80-100k km for iridium plugs should be fine: https://www.myusedcar.ca/when-to-replace-spark-plugs/. The site may not work properly if you don't, If you do not update your browser, we suggest you visit, Press J to jump to the feed. Most pens today (and in the past) use an alloy of materials for the hard surface tipping on the end of the nib. Iridium is harder and more durable than copper or platinum, but more expensive. It also works as catalysts for ammonia and acetic acid reaction. Outside of their own marketed testing, I can't find any real comparison of them vs. iridium, platinum, or conventional copper plugs. Its prices more than quadrupled in the same period, from $38 an ounce at the end of 2016 to $188 an ounce. Many, many years ago, it was not the case that they all had copper and so calling them "copper" was accurate. First, you don't need anti-seize. New comments cannot be posted and votes cannot be cast, Cartalk is full of redditors with a wide variety of automotive background ranging from professional mechanic to guys who have restored entire cars in their garage. Here's the copper thing. 2 NGK Spark Plugs is introducing the latest technology in high ignitability spark plugs to the automotive aftermarket: NGK RUTHENIUM HX â¢.

Updated April 22, 2020 by Kevin. If you go to NGK page and search the fiesta st, the only plugs that came back are the Ruthenium LTR6BHX https://www.ngk.com/NGK-Automotive-Parts-c1411.aspx unlike the iridium that don't appear, either on stock heat or 1 step colder Every plug in the Laser Series was designed for an OEM application. As the center electrode wears and the gap increases, demand voltage goes up. Iridium element occurs as natural alloys of Platinum and Osmium. This alloy is composed of a number of elements. Unless there is something REALLY better about ruthenium than iridium, it sure seems like it. Ruthenium Price Chart (USD / Kilogram) for the Last 2 years. They don't last. You can safely re-install spark plugs without anti-seize. We were looking at the material analysis of a Waterman's Green #7 nib tip from the 1930's. Use this form to dynamically generate charts that show metal prices in the units of your choice and for the specified date range (if available). Testing has shown that ruthenium alloy electrodes are capable of providing up to 2X the service life of iridium spark plugs, and 4X the service life of standard nickel electrode spark plugs. Certain spark plugs are more efficient and perform better than others, and each type has a specific use case. Ruthenium HX spark plugs are manufactured in an ISO 11565-certified facility following the latest manufacturing processes and regulations. 0 shares. An iridium plug uses an extremely fine wire (0.5 to 0.6mm or 0.019-0.023-inch) that, because of its small size, can reduce the required coil voltage by as much as 20-percent. 950 Platinum-ruthenium alloy is the opposite. NEW SERIES ON MY CHANNEL GUYS! Dyno tested by Cycle Solutions Inc. Any thoughts on the OE version versus the fancy IX version? I looked at RockAuto and they have 2 different NGK Iridium to choose from. In fact, by applying anti-seize at any point, you are introducing potential points of failure. Contact us for the best spark plug for your vehicle. Iridium has an anti corrosion properties and it is used in special alloy with Osmium metal and that alloy is used in pen tips and compass bearings. That's why car makers don't use them anymore. Torque them to 22Nm (2.2kg-m, 16 ft.-lbs.).". Iridium is 6x harder and 8x stronger than platinum, has a melting point 1,200°(F) higher, and conducts electricity better.. For many years, spark plug manufacturers favored platinum for their long life and performance plugs due to its high melting point. "There is no iridium in the iridium", Kurt Montgomery said to me as we looked over the print out from the EDAX. Autolite was also against the use of anti-seize, saying the same thing about overtorquing and that its nickel-plated plugs didn't need anyting on them. As for better spark performance with Ruthenium, probably not because modern ignition systems are so powerful, thanks to pollution regulations that virtually require very, very good ignition. In response, Before coming to market, all NGK spark plugs must pass extensive testing and quality checks, including acceleration, combustions, mechanical vibration and thermal shock tests. The downside is that they don't keep their Sharp edge very long and they have the lowest resistance to gap erosion. Until a couple days ago, didn't even know Ruthenium was word; anyway, it's marketed as a "performance" plug. From 1944 onward, the Parker 51 fountain pen was fitted with the "RU" nib, a 14K gold nib tipped with 96.2% ruthenium and 3.8% iridium. I mildly abuse my Miata, but it doesn't go on the track. The key to getting the hottest spark is that it must jump from a sharp edge to another sharp edge. These trucks come with either a platinum or iridium plug, which is a long-life plug. They just dont last as long. Otherwise you risk overtorquing and damaging the cylinder head threads or distorting the spark plug shell which causes them to leak. Iridium element is known as the most corrosion resistance metal .  Ruthenium is a component of mixed-metal oxide (MMO) anodes used for cathodic protection of underground and submerged structures, and for electrolytic cells for such processes as generating chlorine from salt water. NGK says not to do it because their thread coating acts like an anti-seize/anti-corrosive, but a bunch of people still swear by the anti-seize. If you can mold platinum-ruthenium without cracking it, it lasts for a very long time. The projected ground is the difference. The rounder the electrode edge, the more energy is lost trying to make the jump. Trust me when I say that research into improving spark plug durability is one of the most important points of spark plug development. For kicks we put the car on a dyno and removed the Factory wires that had 63k miles, as well as a set of NGK R plugs and swapped them with the Granatelli wires and NGK Iridium plugs. Itâs resistant to wear and tear, but because its hardness is so much higher than platinum-iridium, itâs difficult to mold and takes greater skill to work with to avoid cracking it under excessive pressure. You may have a platinum plug though which isn't quite as long-life as iridium. Ruthenium oxide is used to coat the anodes cells for chlorine production in chemical industry. You guys are a wealth of knowledge even if when your opinions differ; much better info than I got in the Miata.net forums. Horsepower comparison test of NGK Iridium sparkplugs versus stock Harley Davidson sparkplugs. The Iridium IXÂ® spark plugs are a single precious metal aftermarket performance plug. Edit: Thanks for all the well-written replies. The move to iridium plugs could potentially be a performance advantage. Of the many current NGK offerings, I'm looking at the OE version (iridium + platinum), the upgraded "IX" version (double iridium), and one that is Ruthenium. I'm definitely inclined to believe NGK, but let me know if I'm misguided. With ever-increasing demand voltages, change intervals have been dropping. With that in mind, two spark plugs, both with the same sharp edges on the electrodes will generate the same hot spark. Some of these plugs have special resistors or multiple ground electrodes, depending on the original equipment requirements. You'd more than likely be fine to 100K, but if you really wanna be safe you could change them at 90K. Every plug in the Laser Series was designed for an OEM application.
