How to Choose the Right Spark Plugs for Your Car

The quickest and most efficient way to choose the right spark plugs is to check your car owner’s manual. There is a section which explains what type of spark plugs should be used. In general, you are going to come across the following types of spark plugs.

Copper spark plugs

Copper spark plugs have a 2.5-mm diameter nickel alloy and a copper core. It has the biggest electrode among spark plugs, but the smaller the diameter, the less power needed to start a spark. Their firing edge also wears out more quickly than other types, so copper spark plugs are more suited for older vehicles and applications.

Copper spark plugs are best for 1970s and older vehicles, and you must not use them on coil plug ignition systems because they will quickly wear out. Copper spark plugs are also not ideal for high-energy ignition systems that don’t have distributors.

Single platinum spark plugs

This is based on copper spark plugs that have a platinum disc set on the electrode. It is made of platinum alloy, which is more durable than nickel. Its edge is maintained up to 100,000 miles, and it is suitable for vehicles with DIS systems and newer cars in general.

Double platinum spark plugs

These are built for waste-spark DIS ignition systems. A waste-spark ignition system has the spark moving from the center’s electrode onto the sides and is for the compression stroke cylinder.

The spark also leaps backward onto the partner cylinder to return to the electrical pulse. The spark is then “wasted” because the partner cylinder is positioned on the exhaust.

If your car manual says you have to use a double platinum spark plug, do so and do not use a single or copper spark plug.

Iridium spark plugs

Iridium spark plugs are more durable than platinum, but they come at a higher cost. To make up for this, manufacturers minimize the center electrode diameter electrode down to 4mm. Iridium spark plugs also have a high-quality fire center which improves its firing capacity.

A lot of new cars need iridium spark plugs for their systems, but as you probably guessed, you cannot interchange iridium with platinum spark plugs.

Spark plugs with a U or V shape

When the spark starts igniting, the side electrode tries to diffuse the flame. To avoid this, most spark plug manufacturers have a V or U-channel on the surface of the side electrode. This enables the flame to expand quickly, while other systems divide the side electrodes to minimize the contact with the flame.

Features to Look For

Always check your owner’s manual for information on what spark plugs to buy. Do not use spark plugs that are not recommended as it is going to reduce your car’s performance and lifespan. The following are some things to keep in mind.

Ease of installation

How easy are the spark plugs to install? Can you perform the installation without any serious problems or complications?

If your car gives you the option to choose between copper, platinum, and iridium, go with iridium or platinum. They are more durable and offer more value for your money.

TIP : When replacing the spark plugs, it is worth paying attention to the condition of the spark plug wires and replace them if necessary.


Look for spark plugs that are built with durability and long-term in mind. Durability is especially important if you drive your car under difficult conditions.

Avoid low-quality spark plugs. Buying these only provides temporary savings since you’ll be replacing them very often, which can waste money and time.

Improves performance

Well-made spark plugs should enhance performance in several ways. Aside from fuel economy, it should also withstand stress.

Gaps are important, though it varies from fixed to adjustable. Check your car’s manual for details for the proper configuration. If you are going with an adjustable gap, make sure to do it properly during installation.


You also have to consider the brand’s reputation. Buy only from the best brand of spark plugs you can trust so you will get maximum value for your money.
