This is the ProTek R/C O.S. P3 "Ultra Hot" Turbo Glow Plug, the exclusive plug of the Samurai 321B Nitro Engine. The ProTek R/C P3 plug is designed for use in most .18 - .28 off-road turbo head engines such as O.S., RB, Novarossi, Werks and Orion. This P3 variety provides ultra hot operation for optimal idling and acceleration. Package includes one plug.

Some things to keep in mind:

  • The smaller the engine, the hotter the plug.
  • The higher the nitro content, the colder the plug.
  • The hotter the day, the colder the plug.

ProTek R/C is an AMain Sports & Hobbies Brand.

ProTek RC O.S. P3 Samurai 321B Turbo Glow Plug (Ultra Hot)
Best glow plug for using in off road,
engine warms faster and eases the tune up,
just replace it a little earlier than a medium-cold,
can be used in all OS based engines, as in picco, reds.

excellent quality with low price, highly recommended
