Subaru / Robin 065-50001-10 Engine Spark Plug Cap

The Subaru / Robin 065-50001-10 Spark Plug Cap connects the ignition lead to the spark plug in engine systems, forming a secured electrical interface for ignition voltage transfer. It is fitted over the spark plug terminal where it maintains a stable connection between the ignition coil output wire and the plug electrode. During engine operation, the cap conducts high-voltage current from the ignition coil through the lead wire to the spark plug, enabling combustion within the engine cylinder. It is used alongside the ignition coil, wiring harness, and spark plug assembly to maintain proper electrical continuity inside the ignition system.
