Advantages of Iridium spark plug over copper and platinum

If you are exceptionally passionate about maintaining your vehicle, you have probably come across the different types of spark plugs (Iridium, Copper, and Platinum). While you may be familiar with the benefits of installing platinum spark plugs, iridium spark plugs can be an attractive option for diesel fueled vehicles. Here is a detailed look at the various advantages of Iridium spark plugs over copper and platinum.

The advantages of an iridium spark plug over copper and platinum often stem from its heat resistant properties. Copper is not recommended for high performance motors as the heat emanating from these motors could cause damage. However, it is valid for any metal candle. Copper has a shorter lifespan than some other metals, such as platinum. Iridium, Copper and Platinum spark plugs are considered for use in the first 100,000 miles. Iridium is considered the standard of spark plug quality and, according to Jalopy Talk, its higher prices reflect this.

Over other types, iridium spark plugs have many great advantages that make them the ideal choice. While most of these benefits are operational, some involve structural integrity and longevity. Here are five advantages of iridium spark plugs over copper and platinum.

1. Energy efficiency

The Iridium spark plug is designed to last twice as long as platinum or copper spark plugs while maintaining a similar amount of heat in the engine. This is done with an electric heater that transfers energy to other cylinder components, rather than sending heat directly into the combustion chamber where it could cause burns that could damage pistons, valves and dampers. other parts. Another benefit is that it doesn’t get as cold after running for a while due to no exposed metal parts, reducing friction between moving parts that can build up.

2. Increases speed

The Iridium spark plug works almost the same as a standard spark plug. However, due to the coating on the tips of its primary electrodes, it has direct voltage transfer into the cylinder, resulting in a very hot spark between each electrode, causing it to ignite the fuel faster.

3. Increase engine power

The Iridium spark plug has a plus of 12 hp per cylinder compared to 10 hp with platinum or copper spark plugs. It also lasts twice as long as platinum or copper spark plugs and reduces engine wear due to less friction and heat buildup caused by oxidation.

4. Clarity of engine ignition

Iridium spark plugs reduce combustion chambers and engines that overheat due to added voltage. It also eliminates the noise caused by a rough spark, which can be out of tune due to mechanical damage in the engine caused by heat.

5. Long service life

The Iridium spark plug has increased longevity due to its ability to transfer energy from an electric heater directly into the cylinders rather than sending it into the combustion chamber, which can damage pistons, valves and other components. other parts. It also has no exposed metal parts as it is electronic so does not subject itself to mechanical wear resulting from oil or water contamination.


The Iridium spark plug offers many benefits to an engine. Although priced higher than other plugs, it lasts twice as long and reduces friction in the engine, resulting in less wear on parts and a more efficient engine overall. As a result, it’s a perfect choice for those who can afford it and want to save money in the long run.

It can be tempting to order spark plugs online, but your car’s spark plugs are essential parts that require careful installation. If not installed properly and secured correctly, they can cause serious damage to your engine, which will cost a lot of money. Additionally, failure to replace the spark plugs in time could cost you more than the original price of the parts. In other words, nothing beats the peace of mind that comes from having a professional help with your car’s maintenance work, like changing spark plugs.
