PLUG SPARK (P/N hsr88) - New Surplus

The hsr88 is a spark plug connector for aircraft piston-engine ignition systems. This shielded, single-conductor interface connects the ignition lead to the spark plug while reducing radio frequency interference. Installed at the plug end of magneto-equipped engine harnesses, the connector maintains electrical continuity and signal integrity in high-voltage ignition circuits.

Installation requires securing per FAA AC 43.13-1B guidance to preserve shielding and insulation integrity. Commonly used in general aviation aircraft with traditional magneto ignition systems.
