Temp Sender Port Plug
Most of the engines that come in to dyno have these ports for temperature sending units. Intake manifolds, Cylinder Heads and Oil Pans are the most common places to find them.
Usually you have to take that fitting out and thread in a pipe plug....
Now with this plug, you can block that port off quickly and save valuble time
My philosophy is to disturb the fewest things when dynoing an engine. With this plug, you can leave the temperature sending unit receiver fitting IN PLACE and just thread this plug in to speed things up.
Fits the common 5/18 x 18 thread senders that fit most mechanical temperature gauges.
