How Often Should Volvo Spark Plugs Be Changed?
Volvo recommends that spark plugs be changed every 30,000-75,000 miles depending on the spark plug type. However, if you drive in stop-and-go traffic or in other adverse conditions, it is best to change them more often.
Types of Spark Plugs
Spark plugs come in different types, and each type has its own advantages and disadvantages. The three most common types of spark plugs are:
- Platinum spark plugs
- Iridium spark plugs
- Copper spark plugs
Platinum Spark Plugs
Platinum spark plugs are the best type of spark plug available. They last the longest and provide the best performance. However, they are also the most expensive.
Iridium Spark Plugs
Iridium spark plugs are a step down from platinum in terms of quality and performance. They don’t last as long, but they’re much cheaper.
Copper Spark Plugs
Copper spark plugs are the least expensive type of spark plug, but they don’t last as long as either platinum or iridium plugs. They’re best suited for applications where cost is more important than longevity.
Spark Plug Selection Criteria
When choosing spark plugs, there are three main criteria to consider:
- Thread size
- Hex size
- Reach
Thread Size
The thread size is the diameter of the thread on the spark plug. It is measured in millimeters (mm). The most common thread sizes are 0.71mm and 1.01mm.
Hex Size
The hex size is the width of the hexagon-shaped part of the spark plug. It is also measured in millimeters (mm).
Reach
The reach is the length of the spark plug, from the top of the threads to the tip of the electrode. It is measured in millimeters (mm).
