Description
Overview:
This Spark Plug Boot is a genuine Stihl component designed for the MS500i and MS500i-W chainsaws (OEM No. 1147 405 1000). Made from a durable, heat- and oil-resistant elastomer in black, it insulates the high-voltage connection and forms a weather-resistant seal over the spark plug terminal. By shielding the plug from dirt, moisture, and vibration, it helps prevent arcing and misfires, supporting consistent starting and smooth running. The boot fits onto the ignition lead and seats firmly over the spark plug, protecting both the plug and lead from wear in demanding conditions. Built for professional and heavy-duty use, it withstands the high temperatures and harsh environments common to forestry, arborist, and landscaping work. This is a Genuine Part for assured fit and performance.
