You can find spark plugs in a variety of different metal combinations, including aluminum spark plugs, iridium plugs, platinum and more. Because iridium is costly, iridium spark plug manufacturers reduce the diameter of the center electrode to as little as .4mm. NGK Spark Plugs has been developing spark plug technology since the 1930s and manufacture plugs for every type of automotive engine, as well as for motorcycles, marine, horticultural, plant and many other applications. Quick view. plugs, a spark plug socket and an installation tool. Denso's patented Iridium alloy is more durable than even Platinum, allowing the center electrode to be shrunk to only 0.7 mm in diameter. Other options New from $35.99. Read about company.

Iridium Performance Spark Plug Set for BMW. series HELLA Platinum and Iridium Pro oﬀer ultimate performance and power over a longer service life, ideal for both spare part replacement as well as for car enthusiasts looking to upgrade their car performance. Pulstar’s uniquely effective ignition technology is built on 30 years of innovation in pulsed power. Iridium, like platinum, is a precious metal and has extraordinarily superior properties for a spark plug electrode, for example high-temperature withstand, high strength, and low resistance. Because of that, iridium spark plugs have the greatest durability and allows you to get the most possible use out of them. Quick view. Some standard (Original Equipment) plugs are Iridium or fine wire platinum types, these may already provide the ultimate performance and service life for your particular engine.

The ground electrode will wear out first. 3Highly Corrosion Resistant, Burnished Nickel Plating Burnished nickel plating on the housing, a high level of corrosion resistance has been realized. $40.28 $ 40. Iridium metal is employed when high corrosion resistance at high temperatures is needed, as in high-performance spark plugs, crucibles for recrystallization of semiconductors at high temperatures, and electrodes for the production of chlorine in the chloralkali process. IRIDIUM . This produces a dramatic improvement in ignitability and spark plug life. The same plug may be specified for several different engines, requiring a different gap for each. You must have guessed that iridium is harder than platinum. The spark plug gap is the amount of space between the center and side electrodes of each spark plug, and is very important when it comes to choosing the right spark plug for your needs. When spark plugs are new, the resistance value is between 500 and 3000 ohms. But once the plug’s resistance value exceeds 5000 ohms, the plug should be replaced.
