Description
Overview:
This Spark Plug Boot is a Genuine Stihl part designed for handheld petrol machines such as blowers, vacs and mistblowers, including the BR 200 and BG 56. It is a black, elbow‐style cap made from a durable, heat‐resistant rubber compound with an internal terminal that grips the spark plug securely. The boot provides reliable high‐voltage insulation between the ignition lead and the spark plug, helping to prevent arcing, moisture ingress and vibration‐related faults. Its compact 90‐degree form helps route the HT lead neatly and reduces strain at the plug. Built to Stihl specifications for fit and performance, it restores dependable starting and smooth running, making it a practical service replacement for worn or cracked caps.
