Iridium center is too hard to be six times harder than platinum with extremely high durability.Iridium center is made of fine wire electrodes, ensuring high durability but less than laser.The platinum spark plus is copper, which ensuresa highly focused spark.
It reduces Quenching.It improves throttle response.It prevents flashover.
It can increase heat dissipation that can prevent overheating.Highly durable in extreme heat.Extremely high durability against high heat.
The insulator is made of high-grade alumina silicate ceramic.The insulator is not of high-grade aluminum silicate insulator.The insulator is of High-grade alumina silicate ceramic
Made of precious double metalMade of single precious metal.Both single and double platinum are available.
It has a wider center electrode.The center electrode of it is narrow.The platinum is available in both wide and narrow options.
The lifespan of a Laser is around 100,000 Km.Iridium IX provides a lifespan of 60,000 km.The lifespan of the Platinum NGK spark plug is up to 100,000 miles
Highly DurableDurable but less than the laser.Highly durable more than any of these.
It will cost more than the iridium IXIt will cost less than the laser iridium.It is a little costly.

Both Laser Iridium and Iridium IX are good options. One can choose any of these. However, the pick will depend on the user’s circumstances. If one is looking for a good option at a low price, one can go for the Iridium IX.

The last one is platinum, and it will be available in two types like iridium. This one is popular for its fuel efficiency, long life, and excellent performance.


Another important consideration is the material of the spark plug. The material will decide the overall performance of the device. As we already describe the type, the material type is the same. One can choose either copper or delirium, or platinum.

However, platinum will be the best option if the buyers do not have budget issues.

Heat Range
