Zenoah K140072111 Spark Plug Cap G380PU (W/O PACKING)  [K140072111]

Spark Plug Cap for G380PU

This Zenoah K140072111 spark plug cap is an RC-scale replacement part intended for use with the G380PU family as indicated in the product name. It serves the basic function of providing a secure electrical connection between the ignition lead and the spark plug on small model engines, keeping the ignition path insulated and stable during operation.

Compatibility is limited to what is stated in the product naming, so confirm fitment with your G380PU engine assembly before installation. The item is supplied without original packing as noted in the title, which can affect how the part is handled or stored prior to fitting.

For installation, seat the cap firmly onto the spark plug terminal and ensure the ignition lead is fully engaged to avoid intermittent contact. Inspect the cap for cracks, hardened insulation, or oil contamination before reuse; replace if signs of damage are present. Routine checks help maintain consistent ignition timing and reliable starts during running or tuning sessions.

In tuning and maintenance workflows, this cap is a basic consumable: a direct replacement can reduce ignition faults that mimic carburetion or ignition timing issues, so include cap inspection when diagnosing inconsistent idle or hard starting on G380PU-equipped models.
