Quick Spark Plug Summary

This CHAMPION RCJ4 spark plug is made as a replacement ignition electrode suitable for use in Zenoah G230PUH and G230PUM engines. It is intended to restore dependable spark performance for nitro RC engine operation when fitted correctly.

Fitting is straightforward for hobbyists experienced with glow engines: remove the old plug with a spark plug socket or appropriate wrench, clear the thread and sealing washer area of debris, hand-start the new plug and then finish tightening with the socket. Confirm the plug is seated correctly and avoid cross-threading or excessive torque.

During routine tuning and maintenance the plug helps maintain stable ignition timing and combustion. Inspect the electrode gap and overall condition at regular intervals, replace if fouled or damaged, and consider the plug when diagnosing low idle, irregular running, or hard starting in nitro-powered RC models.
