Ngk iridium spark plugs
The iridium plugs might cost slightly more than the copper spark plugs, but it’s still worth it because you’ll be paying for quality. On top of that, the electrical resistance of iridium is better than copper, which also adds to its performance and longevity. Thus, it is natural for consumers to prefer these spark plugs as they give them the value for money. You will not have to replace it as frequently as you do with the copper plugs. On the other hand, the iridium spark plugs can last a really long time. Thus, it is always a good idea to have the spark plugs checked out at every service & change if its need, so that you don’t have to deal with surprises later on. It will bring down the performance of your engine considerably. However, iridium makes the best spark plugs for several reasons.Ī major downside to copper spark plugs is that they have to be replaced soon because the heat inside your engine and the sparks produced make the copper start deteriorate with time. Thus, it should not be surprising that copper is also chosen for spark plugs. How are iridium spark plugs different from the regular ones?Ĭopper is one of the best conductors of electricity, which is why it is used in tubing and wiring. This is reason why it has a small electrode present right in the center. Thus, you get to make the most of using highly durable spark plugs in your vehicle.Ĭoncentrated Spark: The electrical spark that generates from the iridium spark plugs are highly concentrated and strong that helps in quick combustion. The material makes iridium spark plugs the hardest in the market.

Given below are the three benefits you can derive from resorting to high performance spark plugs made of iridium:Įxtended lifespan: The iridium spark plugs usually have a longer lifespan that keeps you free from worries for a long time.Įnhanced durability: Iridium has a silvery-white metal that is usually harder compared to platinum. The top three benefits of using iridium spark plugs Here are a few more things that you must know to have a clear idea about the difference between iridium spark plugs and regular spark plugs. Furthermore, these plugs are wear-resistant and consistent by nature. These spark plugs also have amazing longevity, which means you will not have to go on changing the spark plugs too frequently. They offer a complete combustion and ensure a better performance. The main property of the iridium spark plugs is that their electrode material comes with a high melting point. Spark discharge at intermittent gaps burn away the carbon on the insulator to suppress a decline of insulation resistance.Iridium is an extremely durable metallic element, which makes it a great fit as the material for spark plugs. This reduces the carbon accumulation on the insulator. The small clearance between the insulator supplementary gap prevents the carbon-included combustion gasses from entering the gas volume. Spark discharge at the supplementary gap burns away the carbon on the insulator to suppress a decline of insulation resistance.
Semi-surface discharge plugs burn away the carbon on the insulator nose to suppress a decline of insulator resistance. The wide gap of semi-surface discharge type improves ignition capability and is less sensitive to voltage requirement increases due to gap growth. This type of spark plug can be further classified into the semi-surface discharge type, supplementary gap type and intermittent discharge type. A surface discharge spark plug is designed to create a spark along the insulator nose at the firing end.
