O.S. Engine OS71641500 Turbo Glow Plug P5 Hot - Ignition Element for Nitro R/C Engines  [OS71641500]

Product Brief — Turbo P5 Hot

This turbo-design P5 HOT glow plug is an ignition component intended for nitro model engines. The P5 rating identifies a relatively hotter filament compared with lower-numbered plugs, which alters the filament thermal profile and thus the way the engine lights and idles.

The plug can make cold starts easier and help maintain a steady idle for engines that prefer a higher-heat element. In setup work, swapping plug heat ranges is one tuning tool used in concert with needle and carburetor changes; the plug modifies only the filament temperature response and not the fuel delivery system.

Installation advice: fit only to compatible threaded engines, use the correct glow-plug spanner, and take care to avoid over-tightening which can damage threads. Ensure a clean seating surface and verify engine start and idle before making further adjustments.

Safety and handling: intended for use with model engines only. Do not touch the filament area while it is hot and follow standard precautions for handling nitro fuel and engine components.
