O.S. Engine OS71641400 Turbo Glow Plug P4 Super Hot for Nitro R/C Engines  [OS71641400]

Key features of the P4 Super Hot plug

This turbo glow plug functions as an ignition component for nitro R/C engines. The P4 Super Hot classification means the filament operates at a higher heat range, which can shorten warm-up and stabilise idle under certain tuning conditions.

Compatibility reminder: designed for nitro R/C engines, not electric systems. Always check thread size and heat range compatibility with your engine manual before fitting to avoid improper interchange.

Maintenance and installation: allow the engine to cool before removing the old glow plug. Fit the new plug by hand to engage threads, then use the correct wrench to tighten carefully without over-torquing. After fitting, perform a brief break-in and re-check the plug after the engine reaches normal temperature.

Durability and tuning: a super-hot plug can improve starting consistency and idle in some setups, but may accelerate wear in others depending on use and fuel. Monitor plug condition and engine response when making tuning changes, and replace plugs if starting or combustion quality deteriorates.
