This is the Dynamite Head Lock Glow Plug Wire for the T-Maxx (all versions), Revo 2.5 & 3.3, Jato 2.5 & 3.3, and all other EZ-Start equipped Traxxas vehicles.  This wire hooks more securely to the glow plug, and it is more durable than the stock wire.  Manufactured by Sullivan for Dynamite, the Head Lock Glow Plug Connector lets the fun go on without interruption from loose glow plug connections. Its specially designed Head-Lock design keeps it securely fastened to the glow plug better than the stock connector that comes with the Traxxas vehicles. Machined to last from stainless steel, this very well may be the last glow plug connector you ever need.
