ProTek RC PTK-2554 N4 Hot Standard Glow Plug (.12, .15 and .18 Engines)
The ProTek R/C N4 Medium Hot Standard Glow Plug is a great plug option for .12 to .28 size engines used in monster trucks such as the original and newer 2.5 and 3.3 Traxxas T-Maxx trucks. This plug is recommended for slightly warmer ambient temperature conditions than the N3 and will produce more power. This plug is recommended for higher nitro content fuels (10-30%).
NOTE: For Traxxas applications, use one washer. For O.S. engines use two washers.
