Spark plugs for Subaru WRX and WRX STI products can be a bit of a mystery to some people, so we thought we’d take a moment to explain what each one does and what to look for when choosing one. The first thing to understand is that there are two types of spark plugs in the Subaru WRX and WRX STI engine: wet and dry. Wet spark plugs use oil to help create a spark, while dry plugs rely on electricity alone. Wet plugs are generally preferred in street vehicles because they provide a better firing sequence and are less likely to foul. Dry plugs are good for higher performance applications where reliability and long life are key, such as drag racing. When shopping for spark plugs, the most important thing to look for is the type of spark plug recommended for your vehicle. The next thing to consider is the electrode material and the electrode design. The electrode material is what makes the spark. In the wet plug system, the electrode is made of a metal that has been soaked in oil. When the spark plug is fired, the heat from the spark causes the metal to vaporize and create an electric spark. In the dry plug system, the electrode is a solid piece of metal that is directly connected to the spark plug wire. When the spark plug is fired, the heat from the spark causes the metal to vaporize and create an electric spark. The electrode design is what determines how the spark is created. There are three types of electrodes: center-post, round, and hex. Center-post electrodes are the most common and are located in the center of the spark plug. They are designed to create a strong spark that lasts long. Round electrodes are located on the outside of the spark plug and are designed to create a quick and powerful spark. Hex electrodes are located in the center of the spark plug and are designed to create a medium-strength spark.
