This ignition module is a genuine replacement for Stihl MS231 and MS251 chainsaws, designed to ensure reliable starting and smooth engine performance. It replaces OEM number 1143 400 1315 for a perfect fit. The module features a resin-encapsulated body with a laminated steel core and copper windings, protecting the electronics from vibration, dust, and moisture in demanding work conditions. Mounted near the engine flywheel, it works with the existing flywheel magnet to accurately time the high-voltage spark under load, keeping your chainsaw running efficiently.
