Spark Plugs

Refine Results

SubaruOnlineParts offers authentic spark plugs that serve as catalysts to make your engine run. This equipment helps you avoid roadside accidents and maintains the engine's performance during the city and off-road drives. You can discover original equipment manufacturer (OEM) spark plugs for old models of Justy to newer WRX vehicles.

Ensure Your Car's Performance with OEM Spark Plugs

A spark plug consists of a housing, an insulator, and electrodes. The casing serves as the insulator's cover, and it also attaches the spark plug to the engine. The insulation then prevents the escape of heat from the unit's electrodes. This material eliminates the appearance of black streaks on the spark plug, which indicate leaking voltage from the equipment. Lastly, the electrodes conduct electricity that generates the spark, which is essential to your engine.

This tool is an essential part of every car. It provides the needed spark that stimulates the fuel and air mixture. This process makes it possible for your engine to produce power. Hence, a spark plug is responsible for starting your engine. A malfunctioning spark plug then causes issues like poor gas mileage, engine misfire, and slow acceleration.
