Husqvarna Trimmer Spark Plug574519601

This is a genuine spark plug for your trimmer. 

The spark plug creates a spark that ignites the fuel-air mixture in the engine. This is what gets your trimmer started and allows it to cut through grass and weeds effortlessly.

If the engine runs unevenly or misfires while you're using it, that's another sign that the spark plug might be failing. You might notice it sputtering or losing power when you use it. Change it with this replacement part.

This spark plug for your trimmer is from Husqvarna. Also fits McCulloch trimmers.

Before ordering, please verify that this part is suitable for your model using our compatibility checker.
