the material which the central electrode is made of - yttrium, tungsten, platinum, iridium, palladium. number of electrodes - with one negative electrode (simple) or multielectrode. Here are the main features by which the types of spark plugs are distinguished: Nowadays a large number of various spark plugs are produced. Will it be platinum spark plugs? Copper spark plugs? Iridium spark plugs? How do you know what the best spark plugs are? In this article we will explain the difference between platinum spark plugs, copper spark plugs, iridium spark plugs and others. You will see at least four different types of spark plugs from at least three different manufacturers. When it's high time to replace the spark plugs in your car, you're likely to come across a wide range of choices. And combustion of fuel in the catalyst is extremely undesirable, it can be broken down. An ignition failure causes the entire air-fuel mixture not burned out in the cylinder is transferred to the exhaust system. The efficiency and performance of the engine depends directly on how efficiently the spark works. The purpose of this part is to convert the voltage from the ignition coil into a spark, thus igniting a mixture of fuel and air.

If you’d like help deciding whether iridium spark plugs are worth it for your application, or to explore the alternatives to iridium spark plugs, we’d be happy to help you make the best choice for your business. Iridium spark plugs are the most expensive spark plug model on the market, but in many cases they are worth the investment, as the premium price also comes with high performance and reliability. Making The Right Choice For Your Business This makes ignitions faster and more reliable, and also reduces power consumption. Iridium spark plugs are better at starting engines than other types of spark plug because the spark is highly concentrated in the central electrode, and consequentially requires less voltage to operate. Furthermore, iridium spark plugs perform better at high temperatures, being less susceptible to corrosion and deterioration than other models.Ĥ) Iridium Spark Plugs Are More Efficient For high temperature combustion chambers, therefore, iridium spark plugs are sometimes the only option. Iridium has a high melting point of 2460☌, which is superior to both platinum (1768☌), and copper (1084☌). Iridium is part of the platinum group of metals but is around eight times as strong as platinum itself, meaning that an iridium spark plug can take a lot of damage before it starts deteriorating, and is less prone to unexpected failure.ģ) Iridium Spark Plugs Have Greater Temperature Resistance This helps keep repair bills down and reduces the total lifetime cost of ownership of your engine. On average, an iridium spark plug might last 3000 to 4000 operating hours. IRIDIUM SPARK PLUGS UPGRADE
However, despite the higher cost, iridium spark plugs are still the best high-performance option, for the following reasons:īusinesses that upgrade to iridium spark plugs from alternative metals always report a longer component lifespan. All these factors increase the relative cost of iridium spark plugs. Additionally, iridium is complex to extract from its ore, and the resultant metal is brittle and difficult to work with. The price of iridium has risen steeply during 2021 and is currently the highest priced of the precious metals regularly traded on the commodities market. Iridium is an extremely rare metal that is only mined in certain locations, and global supply has been severely affected by travel and processing restrictions during the pandemic. Iridium spark plugs cost more than other varieties because of the scarcity of iridium itself. Request a Callback Why Are Iridium Spark Plugs So Expensive?
