The average price of a Mazda spark plug is between $2.89 and $10.19.

Mazda spark plugs are a vital part of the ignition system in your Mazda vehicle. Spark plugs are responsible for igniting the air-fuel mixture inside the combustion chamber, which is necessary for the engine to run. The spark plug is connected to the ignition system by a spark plug wire, which carries the high voltage electricity needed to ignite the air-fuel mixture. The spark plug is also responsible for controlling the amount of spark that is produced, which helps to ensure that the engine is running at its optimum efficiency.

The ignition system in a Mazda vehicle consists of several components that work together to create the spark needed to ignite the air-fuel mixture. The first component is the spark plug itself, which is connected to the ignition system by a spark plug wire. The spark plug wire is responsible for carrying the high voltage electricity from the ignition system to the spark plug. The spark plug then uses this electricity to ignite the air-fuel mixture inside the combustion chamber.

The next component in the ignition system is the ignition coil, which is responsible for transforming the low voltage current from the battery into the high voltage current needed by the spark plug. The ignition coil is connected to the spark plug by a spark plug wire and is responsible for controlling the amount of spark that is produced.

The last component in the ignition system is the distributor, which is responsible for routing the high voltage current from the ignition coil to the spark plugs. The distributor is connected to the ignition coil by a spark plug wire and is responsible for controlling the timing of the spark.

These components work together to create the spark needed to ignite the air-fuel mixture in the combustion chamber. Without a properly functioning ignition system, your Mazda vehicle will not run properly. Therefore, it is important to make sure that all of the components of the ignition system are in good working condition. If any of these components are not functioning properly, it is important to have them replaced as soon as possible.

Signs of Faulty Mazda Spark Plugs

Mazda spark plugs may be faulty if you notice any of the following signs:

  • Poor engine performance: If your Mazda spark plugs are not working properly, you may notice a decrease in engine performance. Your car may feel sluggish when accelerating or may have difficulty starting.
  • Increased fuel consumption: Faulty spark plugs can cause your car to use more fuel than usual. This can be seen in an increase in fuel consumption.
  • Engine misfiring: When spark plugs are not working as they should, your engine may misfire. This can cause your car to jerk or lurch when accelerating.
  • Rough idle: Faulty spark plugs can cause your engine to idle roughly. If your engine is shaking or vibrating more than usual, this is a sign that something is wrong with your spark plugs.
  • Check engine light: If your car’s computer detects a problem with the spark plugs, it will turn on the check engine light. If this light is illuminated, it’s time to get your spark plugs checked out.

If you notice any of these signs of faulty spark plugs in your Mazda, it’s important to have them checked out as soon as possible. Ignoring the issue can lead to further damage to your engine and costlier repairs down the road.

Types of Mazda Spark Plugs

There are several types of spark plugs available for Mazda vehicles, each with their own unique characteristics and performance.

The most common type of spark plug used in Mazda vehicles is the copper spark plug. Copper spark plugs are the most basic type of spark plug, and they offer good performance, reliability, and affordability. Copper spark plugs are also long-lasting, as they can last up to 60,000 miles.

Another type of spark plug available for Mazda vehicles is the iridium spark plug. Iridium spark plugs offer improved performance and fuel economy, as they have a higher spark energy than copper spark plugs. Iridium spark plugs also tend to last longer, up to 100,000 miles.

Platinum spark plugs are also available for Mazda vehicles. Platinum spark plugs offer improved performance and fuel economy, and they can last up to 120,000 miles. However, platinum spark plugs are more expensive than copper or iridium spark plugs.

Finally, double platinum spark plugs are available for Mazda vehicles. Double platinum spark plugs offer improved performance and fuel economy, and they can last up to 150,000 miles. Double platinum spark plugs are the most expensive type of spark plug available for Mazda vehicles.

No matter which type of spark plug you choose for your Mazda vehicle, it’s important to ensure that they are properly installed and maintained. This will help ensure that your vehicle runs smoothly and efficiently.


Mazda spark plugs typically last between 30,000 and 50,000 miles. Spark plugs are essential for an engine's proper functioning, and they should be replaced regularly to ensure optimal performance. Spark plugs are essential for igniting the air/fuel mixture in the combustion chamber and can become fouled, worn, or corroded over time. When spark plugs become worn or fouled, they should be replaced to ensure optimal engine performance.

To ensure your spark plugs are working properly, it is recommended that you have them checked and replaced every 30,000 to 50,000 miles. This is especially important if you drive in a lot of stop-and-go traffic or if your vehicle is used for towing or hauling heavy loads. If your spark plugs are not replaced regularly, they can become worn out, leading to poor engine performance, increased fuel consumption, and even engine damage.

It is important to use the correct spark plugs for your Mazda. Using the wrong spark plugs can lead to poor performance and even engine damage. If you are unsure of which spark plugs to use, consult your owner's manual or a certified Mazda technician.
