Like most metals, finely divided iridium powder can be hazardous to handle, as it is an irritant and may ignite in air. How long have you had your Ruthenium plugs? Otherwise you risk overtorquing and damaging the cylinder head threads or distorting the spark plug shell which causes them to leak. This means there’s an even greater reservoir of voltage at the coil if the cylinder requires it. 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. It has 130,000 miles on it and I was wondering on which spark plug to get. Fine-wire plugs are supposed to better, and Bosch came out with them in the 1990s or late 1980s but still offers more conventionally tipped platinum and iridium plugs, and some people have reported compatibility problems with those fine wire plugs, even in VW Golfs. 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. All dual precious metal plugs are designed to provide maximum longevity. 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. [55] Note that this is not you are guaranteeing failure, but increasing risk or creating risk where none otherwise existed before. I always get the oem brand because that works the best for your car. #Markvlogs #NGKVSDENSO #SPARKPLUGBATTLE #Hyundai #EonHi Guys!Welcome back to my Channel!GOOD DAY GUYS! 5 Types of Spark Plugs: Copper vs Iridium vs Platinum vs Double Platinum vs Silver. For the OE Iridium series, dual precious metal means iridium on the center tip and platinum on the ground electrode. You'd more than likely be fine to 100K, but if you really wanna be safe you could change them at 90K. Look at the flame propagation and yes the older nickel alloy plugs are better than iridium but not ruthenium. Precautions[]Iridium in bulk metallic form is not biologically important or hazardous to health due to its lack of reactivity with tissues; there are only about 20 parts per trillion of iridium in human tissue. 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. [54] 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. 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. It also has a HKS Super Power Flow intake and a Genie cat-back exhaust. This means that it needs less current to produce a spark. Before coming to market, all NGK spark plugs must pass extensive testing and quality checks, including acceleration, combustions, mechanical vibration and thermal shock tests. So, a spark plug with a better center electrode material performs better by being more resistant to gap growth (higher durability). Copper plugs actually perform better than precious metal plugs. 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). The projected ground is the difference. Id stick with what the manufacturer recommends. Compare Palladium vs Ruthenium of the Periodic Table on all their Facts, Electronic Configuration, Chemical, Physical, Atomic properties. Every plug in the Laser Series was designed for an OEM application. Ruthenium is a transition metal found in the middle of the periodic table. It’s resistant to wear and tear, but because its hardness is so much higher than platinum-iridium, it’s difficult to mold and takes greater skill to work with to avoid cracking it under excessive pressure. They also have the Denso Iridium spark plugs ($9.76). Yes, don't use anti-seize. In fact, by applying anti-seize at any point, you are introducing potential points of failure. They are a great option for modified engines, and where recommended, are appropriate replacements for OEM spark plugs. Updated April 22, 2020 by Kevin. First, you don't need anti-seize. The only thing nickel spark plugs are better at is price. Certain spark plugs are more efficient and perform better than others, and each type has a specific use case. Experiments don't start in the market, nor are they done for aftermarket (when it comes to design changes like center electrode material). 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. As far as performance, they will all perform the same (except for copper). Simply select a metal and a unit to display the price. A related question is whether to apply anti-seize. The nickel coating on the threads works every bit as good, if not better than anti-seize. With that in mind, two spark plugs, both with the same sharp edges on the electrodes will generate the same hot spark. It all comes down to how long the electrodes hold a sharp edge and resist gap erosion. Ruthenium HX spark plugs are manufactured in an ISO 11565-certified facility following the latest manufacturing processes and regulations. Every 80-100k km for iridium plugs should be fine: https://www.myusedcar.ca/when-to-replace-spark-plugs/. If you can mold platinum-ruthenium without cracking it, it lasts for a very long time. 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 ‘next new thing’, charging more, and profiting handsomely as a result? 950 Platinum-ruthenium alloy is the opposite. Outside of their own marketed testing, I can't find any real comparison of them vs. iridium, platinum, or conventional copper plugs. Have an answer or just a good tip? Iridium IX® plugs are an excellent upgrade from standard nickel plugs. It also works as catalysts for ammonia and acetic acid reaction. Contact us for the best spark plug for your vehicle. Iridium IX plugs are an excellent upgrade from standard nickel plugs. It also works as catalysts for ammonia and acetic acid reaction. Less resistance means more energy goes into the spark which = hotter spark. It is used for producing chip resistors and contact. In response, DO NOT coat the ground strap. So, I need spark plugs for my 2006 Miata. However, they are NOT a one-time thing. The Iridium IX® spark plugs are a single precious metal aftermarket performance plug. ), Looks like you're using new Reddit on an old browser.

Ruthenium Price Chart (USD / Kilogram) for the Last 2 years. It's an oxymoron. Many, many years ago, it was not the case that they all had copper and so calling them "copper" was accurate. If you are looking for spark plugs that last longer, iridium plugs are the best choice. 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. Until a couple days ago, didn't even know Ruthenium was word; anyway, it's marketed as a "performance" plug. Any thoughts on the OE version versus the fancy IX version? Its prices more than quadrupled in the same period, from $38 an ounce at the end of 2016 to $188 an ounce. When it comes to electrical resistance, the difference in resistance is completely negligible. Ruthenium metal also produces as a by-product of the Nickel mining. Here's the copper thing. Ruthenium element has been extracted from used nuclear fuel. Some of these plugs have special resistors or multiple ground electrodes, depending on the original equipment requirements. Below is language from NGK's website on those two: NGK builds two types of iridium spark plugs: OE Iridium and Iridium IX®. Ruthenium oxide is used to coat the anodes cells for chlorine production in chemical industry. As the center electrode wears and the gap increases, demand voltage goes up. If you have an issue with your vehicle someone here can probably help you. Live Spot Prices for PGMs in ounces, all in real-time in 40 currencies. Iridium spark plugs.

You may have a platinum plug though which isn't quite as long-life as iridium. Ruthenium looks like is an experiment by Ngk, I would give ti some time before these plugs prove themselves reliable before buying. (We had to add that last part for good reason, sadly. Metals Daily brings you the fastest, free source of Live PGMs prices in all major currencies 24 hours a day. Unless there is something REALLY better about ruthenium than iridium, it sure seems like it. Trust me when I say that research into improving spark plug durability is one of the most important points of spark plug development. Iridium IX® vs. OE Iridium Spark Plugs. Most pens today (and in the past) use an alloy of materials for the hard surface tipping on the end of the nib. 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. 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). I switch from the ngk iridium 1 step colder plugs that everyone uses, to the new ngk ruthenium 1 step colder plugs. I looked at RockAuto and they have 2 different NGK Iridium to choose from. With ever-increasing demand voltages, change intervals have been dropping. Got a juicy car meme?

The downside is that they don't keep their Sharp edge very long and they have the lowest resistance to gap erosion. However, the coating is a one-time thing. 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. Tighten spark plugs to 25 ft.-lbs.". After a certain point, it will misfire due to the large gap. The rounder the electrode edge, the more energy is lost trying to make the jump. 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. In addition, the plugs are perfect for a power-hungry car because the center electrodes are small. 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 But the center electrode material in "copper" spark plugs is nickel.
