Description
Overview:
This Genuine Husqvarna ignition module assembly is the spark-generation unit for 2‐stroke chainsaws, designed to deliver a consistent high-voltage pulse to the spark plug under all operating conditions. Built with copper windings on a laminated steel core and sealed in a high‐temperature, impact‐resistant polymer housing, it withstands vibration, heat and moisture typical of forestry work. It is a direct replacement for OEM No. 581 72 36 04 and supersedes older module 581 72 36‐02 for straightforward servicing. Engineered for the Husqvarna 550XP and 550XPG, it helps ensure quick starts, stable idle and clean acceleration. Ideal for professional arborists and demanding DIY users, it restores correct ignition timing and spark energy without modifying the saw's wiring or mounting points.
