HobbyTech standard spark plug n°4 medium-hot - HTR-GP-N4

The HobbyTech GP-N4 is a standard short-thread glow plug for compatible RC model engines. This #4 glow plug has a medium-hot heat range and is particularly suitable for OS, Alpha, and Force type engines that use this type of glow plug.

On an RC internal combustion engine, the spark plug ignites the air-fuel mixture thanks to its filament. Once the engine is running, the heat produced in the combustion chamber keeps the filament glowing. Choosing a spark plug suited to the engine, fuel, and operating conditions therefore contributes to a smooth idle, good acceleration, and stable operation.

With its medium-hot heat range, the GP-N4 is positioned as an intermediate solution in the HobbyTech range of standard spark plugs. It is a suitable replacement consumable when an engine is designed for a standard short spark plug of this type.

Before installation, it is essential to verify that your engine's cylinder head accepts a standard short-threaded spark plug . Standard and turbo spark plugs have different designs and are not interchangeable without engine compatibility confirmation. Use a suitable spark plug socket and tighten the spark plug carefully to protect the cylinder head threads.

A spare spark plug is a useful accessory in the field box of a nitro RC car driver. It may need replacing when the filament is worn, deformed, or when the engine's behavior indicates that an ignition check is required.
