Zenoah NGK BMR7A spark plug overview

This NGK BMR7A spark plug, sold under Zenoah part K369990569, is an RC-scale ignition spare intended for use with specific small two-stroke Zenoah engine models. It serves as a direct replacement part for engines listed by model code, retaining the NGK BMR7A designation to match original ignition hardware and electrode geometry.

Installation is straightforward for hobby technicians: remove the old plug with the correct socket, inspect threads and the porcelain insulator, hand-start the replacement to avoid cross-threading, and tighten securely without over-torquing. After fitment, verify ignition and idle before normal use.

In tuning and maintenance routines the spark plug functions as part of the ignition system checks—inspect the electrode for wear or fouling, replace when damaged or excessively eroded, and use the plug as a reference point when adjusting carburetion and idle settings.
