4 types of spark plugs (copper vs iridium vs platinum vs double platinum)
You might think that all spark plugs are the same. After all, the general purpose of a spark plug is to generate an electrical current to ignite compressed air and fuel in the combustion chamber.
However, there are some differences when it comes to spark plugs. Some are more efficient and effective than others. It all depends on the type of spark plugs recommended by the vehicle manufacturer.
Each spark plug has a center electrode and a side electrode. Traditionally, these electrodes were made of copper, but now they are made of materials such as iridium and platinum.
Additionally, the replacement electrodes are much smaller than before. This means that less voltage will be required to generate the electrical current for the combustion chamber.
Generally, you will find that the four main types of spark plugs are copper spark plugs, iridium spark plugs, platinum spark plugs, and double platinum spark plugs.
Some have better uses than others, depending on the vehicle you drive. Below, you will find more details about these spark plugs when it comes time to replace them.

copper spark plugs
This spark plug is mainly made of solid copper. Its central electrode is made of nickel alloy and has the largest diameter of the other spark plugs. This means that more voltage will be needed to generate an electrical current.
Nickel alloy is a soft and weak material. That means it won’t last long. Copper spark plugs are best used in older vehicles that do not have high electrical requirements.
- Advantages: – Best for older vehicles manufactured before 1980.
- The drawback: – that they don’t last as long. It requires more tension.
iridium spark plugs
Iridium spark plugs will last longer. Iridium is a stronger and more durable metal than platinum. Although you have to pay more money for iridium spark plugs, you get what you pay for.
These spark plugs have a small center electrode, which means they use less voltage to generate the electrical current. That’s why many automakers are starting to recommend iridium spark plugs for their vehicles.
If you have already installed these spark plugs and need new ones, do not switch to platinum or copper, as they will reduce the performance of your vehicle.
- Advantages: – Harder than platinum; Lasts longer; Uses less voltage
- the drawbacks: My friend
platinum spark plugs
A platinum spark plug is similar to a copper spark plug, except that it has a platinum disc on its center electrode that is welded to the tip area. The copper spark plug in this area has only nickel alloy material.
As a result, the platinum spark plug is more durable and can last up to 100,000 miles.
These plugs also generate more heat, which means less debris buildup. If you have a new car with an electronic distributor ignition system, platinum spark plugs are recommended.
- Advantages: – Lasts longer than copper and reduces debris collection.
- the drawbacks: – that it is not the most powerful spark plug on the market

Sparks double platinum
If your dealer’s ignition system is a misfire system, bi-platinum spark plugs are recommended. This system causes the spark plugs to fire twice: once in the compression stroke cylinder and once in the exhaust stroke cylinder.
The spark from the latter is wasted because there is no ignition. The advantage of the wasted spark system is that it is more reliable and is not affected by environmental conditions such as rain or humidity.
- Advantages: Recommended for residual spark systems; Trustworthy
- the drawbacks: Not recommended for electronic DIS
