Iridium spark plugs are a common type of combustion engine ignition device found in industrial engines worldwide. They’re known for their strength, reliability, conductivity, and strong resistance to extreme internal temperatures.
They’re fitted into the engine and connected via a HT lead to the ignition coil. The coil temporarily powers the plug with a fixed electrical voltage. When the engine is started, iridium spark plugs convert this electrical charge into the spark needed to light the air-fuel mixture. (more…)
Industrial spark plugs, unfortunately for both manufacturers and consumers, depend on two of the scarcest and most difficult to process metals on earth – iridium and rhodium. Iridium is an extremely rare metal, with global mining output averaging just 3 tonnes per year. Rhodium, if anything, is even harder to come by, combining extreme rarity with a very complex and expensive ore extraction process. These metals have always been expensive commodities but, fortunately for both manufacturers and consumers, the volumes required to manufacture spark plugs are extremely small.
While spark plugs are universally used in petrol-fuelled internal combustion engines and vehicles, and in gas-powered industrial stationary engines, diesel engines don’t have spark plugs. Instead, diesel engines are fitted with special components called glow plugs, which are similar to spark plugs in some ways but have some crucial differences.

Spark plugs for stationary gas-operated industrial engines must be able to withstand non-stop operation while demonstrating considerable durability over long replacement intervals. The Federal-Mogul/Beru heavy duty spark plug range is manufactured from the highest quality materials and are very resistant to combustion, offering longevity and excellent performance – and they are available now from R & M Walsh.
As iridium spark plugs become worn and dirty, more electrical power is required to produce the spark necessary for ignition. This reduces efficiency and increases fuel consumption – and can eventually lead to misfires and electrical short-circuits. It follows that the cleaner the spark plug’s electrodes, the more powerful a spark the component will produce, at a lower voltage.
Double iridium spark plugs are a special type of spark plug equipped with iridium laser welded onto the centre and ground electrodes. They’re used in industrial combustion engines to convert an electrical charge into an ignition spark, powering a cylinder and piston to create movement. But why are Double iridium plugs considered to be so much better than other spark plugs? Here are five good reasons. (more…)
2000 hours is the average lifespan of a standard industrial spark plug. There are a wide variety of engine faults that can be caused by bad installation, malfunctions, misuse, contamination, or simple bad luck.
All gas-powered combustion engines need spark plugs to run. The spark plugs convert a high-voltage electrical charge into the spark needed to ignite a mixed gas and air intake, turning cylinders and turbines to provide electrical generation or repetitive kinetic motion.
Every high-energy spark plug used in an industrial engine needs to be fixed to a housing chamber by a wrenched socket. This firm casing allows the spark plug to dissipate the immense heat it generates via the cylinder head, and align with its gas and electrical contacts. (more…)
Spark plugs are small and relatively inexpensive components but play a crucial role in gas-powered engines. Damaged spark plugs can reduce the performance output and energy efficiency of an engine, while unexpected spark plug failure can prevent ignition altogether. To avoid unscheduled downtime, it’s important to keep an eye open for the warning signs of spark plug failure. These are the main tell-tale signs that your spark plug’s days are limited, and that it’s time to order a replacement.
