Glow Plug Rossi R4, engine part, cold grade

The Rossi R4 glow plug is a cold-grade engine part made for nitro model engine setups that depend on the right heat range at the cylinder head. Its compact metal construction combines a threaded shaft, a hex body for tightening and a contact tip at the top, creating the functional layout used for installation and engine operation. A copper sealing washer is included and sits between the plug and the engine head to help create the intended seal at the mounting point. The visible thread and hex profile make the part straightforward to position with the correct tool, while the single-plug format suits maintenance, replacement and tuning work on compatible engines. As a dedicated engine component rather than a general accessory, the Rossi R4 belongs in the workshop kit for glow-powered model running where the specified cold rating is required. On the bench, this part fits naturally into routine service before the next driving session or as a direct replacement when an engine needs a fresh plug. The 14 Years age marking is stated in the supplied data for this hobby accessory, placing it in the enthusiast end of model engine maintenance rather than general toy use.
