G380PU Spark Plug Cap K140072111 - Zenoah  [K140072111]

G380PU Spark Cap Overview

This Zenoah K140072111 spark plug cap is a replacement part intended for use with G380PU engines. It provides a secure electrical connection between the ignition lead and the spark plug, insulating the ignition path and helping to maintain a stable spark during operation.

Fitment is limited to the engine family referenced in the product name, so verify compatibility with your G380PU assembly before fitting. The item is supplied without original packing as stated, which may affect storage or presentation prior to installation.

For installation, push the cap fully onto the spark plug terminal and ensure the ignition lead is seated completely to avoid intermittent contact. Inspect the cap for cracks, hardened insulation, or oil contamination before reuse and replace if defects are present. Regular checks support consistent ignition and dependable starting.

As a basic consumable in tuning and maintenance workflows, replacing a worn cap can help eliminate ignition faults that resemble carburation or timing issues, so include cap condition when diagnosing inconsistent idle or hard starting on G380PU engines.
