5 Types of Spark Plugs: Copper vs Iridium vs Platinum vs Double Platinum vs Silver. 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. I always get the oem brand because that works the best for your car. The downside is that they don't keep their Sharp edge very long and they have the lowest resistance to gap erosion. Ë Ë shortens the life of traditional Iridium and Platinum spark plugs. Unless there is something REALLY better about ruthenium than iridium, it sure seems like it. Live PGM Prices. Id stick with what the manufacturer recommends. You'd more than likely be fine to 100K, but if you really wanna be safe you could change them at 90K. The element Iridium was discovered by Smithson Tennant in year 1803 in France and United Kingdom. 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. As the center electrode wears and the gap increases, demand voltage goes up. The nickel or zinc, depending on manufacturer, plating is designed to prevent corrosion and seizing. Iridium spark plugs. 2 NGK Spark Plugs is introducing the latest technology in high ignitability spark plugs to the automotive aftermarket: NGK RUTHENIUM HX â¢.

The only thing nickel spark plugs are better at is price. Less resistance means more energy goes into the spark which = hotter spark. When it comes to electrical resistance, the difference in resistance is completely negligible. Like most metals, finely divided iridium powder can be hazardous to handle, as it is an irritant and may ignite in air. "Copper" spark plugs are a bit of a misnomer these days. Outside of their own marketed testing, I can't find any real comparison of them vs. iridium, platinum, or conventional copper plugs. 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. Lastly choose the number of ⦠The Iridium IX spark plugs are a single precious metal aftermarket performance plug. We were looking at the material analysis of a Waterman's Green #7 nib tip from the 1930's. As far as performance, they will all perform the same (except for copper). 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. Trust me when I say that research into improving spark plug durability is one of the most important points of spark plug development. Any thoughts on the OE version versus the fancy IX version? Ruthenium HX spark plugs are manufactured in an ISO 11565-certified facility following the latest manufacturing processes and regulations. DO NOT coat the ground strap. First, you don't need anti-seize. 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. How long have you had your Ruthenium plugs? Please share as part of the Cartalk community. But the center electrode material in "copper" spark plugs is nickel. 0 shares. Horsepower comparison test of NGK Iridium sparkplugs versus stock Harley Davidson sparkplugs. All dual precious metal plugs are designed to provide maximum longevity.

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. That's why car makers don't use them anymore. In addition, the plugs are perfect for a power-hungry car because the center electrodes are small. Ruthenium element has been extracted from used nuclear fuel. Simply select a metal and a unit to display the price. The projected ground is the difference. Iridium IX® plugs are an excellent upgrade from standard nickel plugs. Ruthenium element has been extracted from used nuclear fuel. I am definitely wanting to get them but I havent seen any Youtuber talk about them. Until a couple days ago, didn't even know Ruthenium was word; anyway, it's marketed as a "performance" plug. However, the coating is a one-time thing. (We had to add that last part for good reason, sadly. 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. It also works as catalysts for ammonia and acetic acid reaction. My google fu skills pulled up no useful real-world info on Ruthenium plugs. This alloy is composed of a number of elements. So, I need spark plugs for my 2006 Miata. Ruthenium oxide is used to coat the anodes cells for chlorine production in chemical industry. 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. It is used for producing chip resistors and contact. Iridium is harder and more durable than copper or platinum, but more expensive. The nickel coating on the threads works every bit as good, if not better than anti-seize. Ruthenium oxide is used to coat the anodes cells for chlorine production in chemical industry. You can safely re-install spark plugs without anti-seize. 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. Contact us for the best spark plug for your vehicle. In fact, by applying anti-seize at any point, you are introducing potential points of failure. 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. Torque them to 22Nm (2.2kg-m, 16 ft.-lbs.).". The rounder the electrode edge, the more energy is lost trying to make the jump. Live Spot Prices for PGMs in ounces, all in real-time in 40 currencies. If you remove the plugs and intend to reinstall them, then you must use anti-seize on the reinstall. No Prius Podcasts. Its prices more than quadrupled in the same period, from $38 an ounce at the end of 2016 to $188 an ounce. Here's the copper thing. Every plug in the Laser Series was designed for an OEM application. The price is about the same and I don't care whether they last 40,000 miles or 75,000 miles. NGK recommended against using platinum plugs with nitrous oxide injection because the platinum sometimes blew off, but that hadn't happened with iridium plugs. Ruthenium metal also produces as a by-product of the Nickel mining. NEW SERIES ON MY CHANNEL GUYS! We love those things. It also has a HKS Super Power Flow intake and a Genie cat-back exhaust. "There is no iridium in the iridium", Kurt Montgomery said to me as we looked over the print out from the EDAX. Have an answer or just a good tip? Compare Palladium vs Ruthenium of the Periodic Table on all their Facts, Electronic Configuration, Chemical, Physical, Atomic properties. They don't last. The key to getting the hottest spark is that it must jump from a sharp edge to another sharp edge. Some of these plugs have special resistors or multiple ground electrodes, depending on the original equipment requirements. 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? With ever-increasing demand voltages, change intervals have been dropping. Look at the flame propagation and yes the older nickel alloy plugs are better than iridium but not ruthenium. They are a great option for modified engines, and where recommended, are appropriate replacements for OEM spark plugs. 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 ⦠950 Platinum-ruthenium alloy is the opposite. 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. I get NKGs for my vw beetle and champion copper cores for my truck. 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. I switch from the ngk iridium 1 step colder plugs that everyone uses, to the new ngk ruthenium 1 step colder plugs. After a certain point, it will misfire due to the large gap. Certain spark plugs are more efficient and perform better than others, and each type has a specific use case. Ruthenium Price Chart (USD / Kilogram) for the Last 2 years. They are a great option for modified engines, and where recommended, are appropriate replacements for OEM spark plugs. This is so incredibly wrong. NGK RUTHENIUM HX⢠ngksparkplugs.com Tech Support: (877) 473-6767 ext. I know alot has been written about this subject but I thought I would share my experience. Below is language from NGK's website on those two: 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. 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). Before coming to market, all NGK spark plugs must pass extensive testing and quality checks, including acceleration, combustions, mechanical vibration and thermal shock tests. Ruthenium demand climbed 9 percent last year to 1.204 million ounces, its highest since 2006. 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. I'm definitely inclined to believe NGK, but let me know if I'm misguided. Yes, don't use anti-seize. It all comes down to how long the electrodes hold a sharp edge and resist gap erosion. First off I have a relatively mildly modified MR2 Turbo: it has a MBC set to 14 psi and a re-programmed ECU by G-Force. 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 There just doesnt seem to be a lot easily accessible info out there about them. 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. Ruthenium is a transition metal found in the middle of the periodic table. 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. You may have a platinum plug though which isn't quite as long-life as iridium. Got a juicy car meme? The Iridium IX® spark plugs are a single precious metal aftermarket performance plug. Not all plugs work in every car. Many, many years ago, it was not the case that they all had copper and so calling them "copper" was accurate. 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. Note that this is not you are guaranteeing failure, but increasing risk or creating risk where none otherwise existed before. Iridium IX plugs are an excellent upgrade from standard nickel plugs. This means thereâs an even greater reservoir of voltage at the coil if the cylinder requires it. So, a spark plug with a better center electrode material performs better by being more resistant to gap growth (higher durability). Edit: Thanks for all the well-written replies. I could get the standard Iridium IX ($6.85) or spend more than double on the Laser Iridium ($14.73). Iridium element occurs as natural alloys of Platinum and Osmium. #Markvlogs #NGKVSDENSO #SPARKPLUGBATTLE #Hyundai #EonHi Guys!Welcome back to my Channel!GOOD DAY GUYS! So really, there's no such thing as a "performance" spark plug. Iridium element is known as the most corrosion resistance metal . You guys are a wealth of knowledge even if when your opinions differ; much better info than I got in the Miata.net forums. A related question is whether to apply anti-seize. [55] 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. Iridium IX® vs. OE Iridium Spark Plugs. 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. 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. However, they are NOT a one-time thing. ), Looks like you're using new Reddit on an old browser. Otherwise you risk overtorquing and damaging the cylinder head threads or distorting the spark plug shell which causes them to leak. It is part of a group of the precious metals group that are also referred to as platinum metals. All dual precious metal plugs are designed to provide maximum longevity. In response, Updated April 22, 2020 by Kevin. These trucks come with either a platinum or iridium plug, which is a long-life 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). OEMs have stopped using them because they won't last through the warranty period. If you are looking for spark plugs that last longer, iridium plugs are the best choice. Since they're pretty easy to change on a Miata, I'd go with copper. Iridium element is known as the most corrosion resistance metal . These two plugs perform similarly, due to their fine-wire tip design, but the service interval is different; the Laser Series are typically designed to last 80 to 100 thousand miles, where as the Iridium IX® spark plugs are designed to last 40 to 50 thousand miles. With that in mind, two spark plugs, both with the same sharp edges on the electrodes will generate the same hot spark. Regarding copper spark plugs: there is a copper center electrode core in every spark plug, whether it's "copper" or precious metal.
