Question: Give as much detail as possible. : I checked into Full Torque spark plug repair kits. I am not sure which insert I need to use for the repair- it gives me two options: Type 1 or Type 3 for my truck.
Which insert would you suggest I use?
Answer: That depends on the type of spark plug you have. The gauge in the kit is used to check the taper on the cylinder head to decide which is the proper inset. It looks like the kit has both or even all 3 types. Contact manufacturer to be sure. So use the instructions in the kit to check your cylinder head taper with the gauge tool.
