All iridium plugs are NOT created equal. All iridium Bosch OE Fine Wire Double Iridium. Please enter a number less than or equal to 2. iridium Spark Plugs. But we need to understand that the main load is carried by two electrodes – central and lateral (a spark passes between them). Regardless of engine, manufacturer or ignition type. Iridium is an element with the atomic number 77 (in Mendeleev D.I.’s system). And even if you pour bad gasoline – the spark plugs is covered with a coating (say, red from additives) or carbon deposits, then everything needs to be put on top of a new one. At first I wanted to tell you a little about iridium and platinum. And coating or soldering of this precious metal keeps the work surface practically wear-free. I picked up the DENSO brand, chose it as usual from the catalog. 6mm fine wire firing pin provides superior ignitability and performance. So we come to the most interesting, but in fact, what is better than the usual iridium option? Two electrodes, opposite each other. This amount is subject to change until you make payment. Over time, this is usually 50-80,000 km, the size of the electrodes becomes smaller, the gap increases and the coil cannot effectively spark (it turns out to be weak), the car is not attracted, and fuel consumption can also increase. However, when you look at their reliability and life span, you will agree that they do complete justice to the price tag. Bosch's iridium spark plug series brings OEM iridium long life plugs to the market, with an iridium fine wire center electrode and iridium/platinum alloy tipped ground electrode. BUT nothing lasts forever, as soon as the deposition of this platinum group metal is destroyed, literally the working surface of the electrode is immediately destroyed. Bosch Spark Plugs for Gen 2 MINI Cooper & S will give you the most out of your car's engine. Iridium Spark Plugs or Regular Spark Plugs – which is better? Bosch Double Platinum Spark Plugs are engineered to deliver both performance and long life, representing the best of OE spark plug technology. Double Iridium firing pin and ground electrode inlay provide 4X longer service life compared to standard copper plugs. Therefore, NGK gives them a life expectancy of 40-50k miles and Denso assigns a recommended replacement interval of 30k miles. You have entered an incorrect email address! There are some differences here, but as many manufacturers believe, they are significant. Copyright © 1995-2021 eBay Inc. All Rights Reserved. Please submit in the comments, so that our other friends can find out. 2022 Mercedes EQE Will Be Best Electric Sedans? Install Tip: Torque new plugs with a torque wrench to min 17 ft lbs. 'width' : 300, Therefore, the spark plugs must match not only the overall characteristics (dimensions, height and thread), but also with gaps and resistance. Please enter 5 or 9 numbers for the ZIP Code. Are The Latest Generation Cars Much Better? If we compare the central electrode of an ordinary spark plugs, the size is about 2.4 – 2.8 mm, but for the iridium version it is only 0.5 – 0.8 mm. WHERE IS THE TRUTH? Spark Plugs Overview, features and benefits Engineered for high performance and long life. We use cookies to ensure that we give you the best experience on our website. As I wrote above, all cars have specific ignition coils, different compression ratios etc. THIS IS NEED TO UNDERSTAND. The center electrode is made of an iron-nickel alloy with the addition of copper and chromium. But the platinum variants (for example, BOSCH Platinum) have a center electrode that is completely platinum, but very thin, which locks (as if poured) into a dense ceramic insulator. Various application options are now distinguished: As we know, this precious metal has excellent melting properties, wear resistance, corrosion and transmission of electric current. If you’re not a fan of the idea of replacing spark plugs every 60,000 miles or so, iridium can reach up to a 120,000-mile life cycle. The ultra fine wire design and laser welded, tapered ground electrode deliver the ultimate in ignitability and high performance. A 0.2mm gap difference, which you may not see visually, can interfere with the performance of your internal combustion engine. If you continue to use this site we will assume that you are happy with it. Bosch OE iridium spark plugs combine a 360 degree continuous laser-welded iridium center electrode, with a laser-welded ground electrode—to provide unmatched quality and OE long-life performance. Iridium spark plugs have extremely fine electrodes while retaining excellent wear characteristics. ACDelco Professional Iridium Spark Plug features the latest technology available. That is why it is made thicker so that it is resistant to aggressive environmental influences. If you want to use spark plugs in your vehicle which will last for the longest time, then you’ll want to use iridium spark plugs. Long Life: Some spark plugs are made to have a longer life. Something went wrong. Bosch Double Iridium Spark Plugs are engineered to deliver both high performance and long life, representing advanced OE spark plug technology. Bosch Double Iridium Spark Plugs are engineered to deliver both high performance and long life, representing the best of OE spark plug technology. That also happens with the resistance of the spark plugs, it has to match your electrical circuit. Bosch Double-Iridium spark plugs are developed to the same high quality as original equipment and engineered for high performance in gasoline engines. Everything is simple here – iron-nickel right with copper and chromium also cannot perfectly withstand the discharge of electricity, temperature, corrosion as opposed to those made of precious metals, it will just wear out and collapse faster (literally within 10-15000 km) , thereby increasing the gap and worsening specifications. A very hard, refractory, silver-white transition metal of the platinum group. Iridium spark plugs feature a fine wire center electrode that is designed to conduct electrical energy better and increase firing efficiency. So, we get a very strong, concentrated spark. If you have the money, you can pay more for iridium options, they really work well and work for a long time, and it seems to me that winter is starting, albeit slightly, but better. Sometimes the middle and side electrodes are doped (if it is clear) – with iridium. 0. Thank you for reading our article and hope you enjoy it. Condition is "New". Trusted seller, fast shipping, and easy returns. I have experience with such an element, and therefore there is something to tell and show, let’s think about the pros and cons.
