Husqvarna 579 20 79-01 OEM Ignition Module for 545, 550 XP Chainsaws 579207901
OEM ignition modules (also known as ignition coils) are a high quality replacement option for your Husqvarna chainsaw. Ignition modules go out for various reasons, but the main culprit is excessive heat. Once they are cooked, your saw loses spark, and you will have to replace it. OEM ignition modules have RPM limiters built in to protect from over adjustment of the carburetor.
