All about Iridium Spark Plugs and the Best Choice for You

Iridium spark plugs are some of the most selected today. They are made of iridium, a hard metallic element with a boiling point of 2500 degrees Celsius. Iridium occurs naturally on earth just like platinum, but it is tougher. Iridium is a super material for making a spark plugs’ electrode. Since iridium as a pure metal is extremely breakable and has poor electrical conductivity, it’s used as an alloy. Iridium’s good properties aren’t enough when it comes to producing the best electrodes.

But when used as alloy of another metal, it generates the most dependable electrode for spark plugs. This electrode has great electric power conductivity and enough level of hardness. Another advantage to using iridium alloy is that an electrode can be made with the tiniest diameter possible. That’s why iridium alloy spark plugs have come to replace the conventional copper electrode. It is more reliable than a platinum-tipped electrode as a result of its thin diameter. This narrow diameter focuses the electrical current, reducing the amount of voltage needed to hop across the spark gap.

A low voltage is excellent because it minimizes the load on your auto’s combustion system. Due to minimal strain, your car is less likely to suffer. Additionally a bigger gap can be backed up without raising the load on your combustion/ignition system. Thus, a larger spark can lead to more efficient combustion, especially, when delivered in the right position and in time. Here is a summary of using iridium spark plugs.

  • More throttle response
  • More service from your spark plugs. They are known to last longer especially if well-designed
  • More engine horsepower
  • Reduced CO2 emissions, so you can take part in preserving the environment for future generations.

Perhaps you are wondering whether you will reap any benefits given your engine type. Engine type not withstanding, iridium alloy plugs work many times better than standard spark plugs. So, don’t hesitate to purchase this plug. Regardless of your engine, you will be able to find an iridium plug that closely matches your current standard version. If you cannot, you should let go of your goal to swap your older version plugs for iridium ones. Second, any engine has a big cylinder capacity and many cylinders.
Due to this versatility, you can choose spark plugs that will fit and function well. If your car uses the older copper spark plug, you will do yourself a big favour by altering them. While you can get all the above benefits, keep in mind that the aftermarket iridium plugs may not be as effective as your original spark plugs. The original spark plugs may have been made of platinum or iridium and therefore could work better than the low quality aftermarket iridium plugs.

As we have a lot of expertise in this area. We would be happy to recommend iridium plugs that you can buy without any regrets. This is none other than NGK Iridium IX Spark Plug. This product boasts very elaborate wiring and so it requires low voltage to do its work. As a result, your vehicle can have longer battery life and your auto can save a lot of power. Additionally, the NGK spark plug has a laser welded centre with a 0.6mm tip and the same centre is iridium tipped. Its ground electrodes are made from double iridium and this increases the products lifespan. As NGK provides a warranty, you can have your products swapped if they develop a problem. Chambers are insulated through ribbed insulation grooves and so your iridium spark plugs cannot misfire. The easy to install plugs are extremely dependable, long lasting and safe.
