Manufactured by Sullivan for Dynamite, the new T-Maxx 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 T-Maxx. Machined to last from stainless steel, this very well may be the last T-Maxx glow plug connector you ever need.
