SELL YOUR USED SPARK PLUGS

Here is a small guide on how to tell the difference between the different spark plugs.

We buy PLATINA and IRIDIUM spark plugs.
COPPER spark plugs are sorted as mixed scrap

Differentiating between copper, platinum and iridium spark plugs is important, in order to get the highest possible compensation. Here are some ways to identify them:

1. The material of the electrode

Copper: Copper spark plugs have a central electrode with a copper core, but the surface of the electrode itself is usually covered with a nickel alloy. These spark plugs usually have a thicker electrode.

Platinum: Platinum spark plugs have a thin platinum disc on the central electrode. This makes the electrode much narrower than on copper spark plugs. The thin platinum coating makes the spark plug last longer and have better performance.

Iridium: Iridium spark plugs have an even thinner electrode than platinum spark plugs. Iridium is a much harder and more heat-resistant metal than both copper and platinum, which allows for an even narrower electrode that provides better spark formation and longer life.

2. Labeling

Marking on the spark plug: Manufacturers often label spark plugs with information that may include the material. For example, letters such as "P" or "I" may be used to indicate platinum or iridium, respectively.

3. Color and surface finish

Copper: Copper spark plugs can have a slightly duller or less shiny surface compared to platinum and iridium, which often look more polished.

Platinum and Iridium: These spark plugs have a more shiny and glossy surface on the electrode.

Checking the appearance of the electrodes and markings on the spark plug are the best ways to distinguish between these types.
